This manual describes the increased functionality of v3.00 firmware, released October 2007. Some of the features described in this manual are not available in older systems. For your convenience, both the Model A704-5 light and wireless controller have quick start instructions that can be found in the following sections: Model A704-5 Light: section 4.2 Model A704-5 Light Quick Start Guide...
) as the maximum exposure limit for viewing for up to 16 minutes. This power density can be produced by a Model A704-5 at the lens surface when actively emitting infrared light. High-power visible-spectrum LEDs also pose an eye safety risk if viewed inappropriately.
Misaligned connector pins can cause damage to system components at power-on. Storage Precautions When in storage, the A704-5 light will require periodic recharging to maximize the life expectancy of its batteries. The interval between recharging is dependent upon the temperature where the light is stored.
Each output mode can be selected by pressing a push button on the light itself or by using the optional wireless controller. If the light needs to be extinguished immediately, a single press of the push button places the light into Standby Mode. When in Standby Mode the Model A704-5 will not illuminate until the next nightfall.
Programming Options There are two options for programming the Model A704-5 light: Push Button: The black push button on the top of the Model A704-5 allows manual programming of the Model A704-5 features and operation. Wireless Controller: The wireless controller is capable of performing all push button operations as well as several advanced operations.
Table 4-1: Overview of Command Levels and Modes illustrates the order of commands and modes for programming the Model A704-5. This table is followed by a description of the light’s operation in each mode. Read this table from left to right.

– such as poor visibility due to bad weather conditions. To activate a high-intensity output mode, use [1, 1] for low, [1, 2] for medium, and [1, 3] for high. Day or night, the Model A704-5 will immediately turn on at the selected temporary high-intensity setting, and will remain on for one hour.

Button Sequence [4, 2]: UCS Status To determine if the UCS is enabled or disabled on the A704-5, use button sequence [4, 2] to request the UCS status. The indicator LEDs will blink 3 times to show the UCS status as follows:...
4.3.4 24-Hour Shutoff If the Model A704-5 senses ambient light levels of 30 lux or less for 24 consecutive hours, it will assume it is being stored and automatically enter Ship Mode to preserve the battery. The ambient light thresholds are set so that a very dark winter season will not cause the Model A704-5 to enter Ship Mode unintentionally.

Owner’s Manual | Model A704-5 Aviation Lighting System Understanding the Controller The A704-5 wireless controller is made of rugged aluminum with a sealed backlit keypad and a 900 MHz transceiver. The wireless controller enables secure configuration and operation of the A704-5 light and is designed to withstand water immersion.
Administrator Mode 5.4.1 User Mode User Mode allows an operator to control one or more A704-5 lights with the operations listed in sections 5.6 Basic User Operations and 5.7 Advanced User Operations. In User Mode, the wireless controller turns off after 60 minutes of inactivity to avoid unauthorized access and to maximize battery life.
Owner’s Manual | Model A704-5 Aviation Lighting System 5.4.2 Administrator Mode Administrator Mode allows an operator access to the following management operations of the wireless controller. Personal Identification Number (PIN) Management Unique Code Sequence (UCS) Management ARCAL Entry In Administrator Mode, the wireless controller turns off after 10 minutes of inactivity to avoid unauthorized access to management operations.
Press the AUTO button Press intensity level LOW, MED, or HIGH Press ENTER A704-5 lights in AUTO Mode located near other lights (within 1 foot) may turn off due to the light emitted from them. 5.6.4 Temporary Operation Mode Lights set to temporary high-intensity operation using the controller will remain at this intensity for 15 minutes before returning to their previously set Autonomous Mode.
To turn off lights: Press LIGHTS OFF Press ENTER Lights in Standby Mode do not accept the Lights Off command; the A704-5 light must be on to accept the Lights Off command. 5.6.9 Emergency Mode Emergency Mode sets all lights in all groups to emergency flash. After 15 minutes the lights will revert back to their previous autonomous state.
The Radio Health Diagnose function sends a command to the lights to display a radio health indication. The A704-5 light continually monitors the health of its radio module and automatically restarts the radio if needed. A count is kept of these restart events; intermittent radio problems are thus automatically recovered from and are very likely to go unnoticed in normal operation.
Owner’s Manual | Model A704-5 Aviation Lighting System Lights with radios that have needed one or more automatic restarts will identify themselves to the remote operator by responding with five flashes: To send the Radio Health Diagnose (Clear) command to the lights:...

A critical low battery condition occurs when the A704-5 batteries have been discharged to a point where the A704-5 cannot resume normal operation and battery damage is likely. In this state, the light will briefly flash about every 10 seconds, and the red and green indicator LEDs will light up during the cycle. Battery replacement is recommended, although some batteries will respond to the following advanced recharge method.
Optional Airport Mounting Stake The Model A704-5 Aviation light can also be installed using an optional airport mounting stake. Made of galvanized steel, the airport mounting stake is suitable for permanent installation in earth and gravel. The 30"...
Owner’s Manual | Model A704-5 Aviation Lighting System Model A704-5 Operational Maintenance/Diagnostics This section describes the procedure for performing routine maintenance checks on the Model A704-5 runway lighting system. Routine maintenance checks will ensure the system is operational and ready in the event of an emergency.
Do not place your Model A704-5 closer to the light source than recommended in Table 9-2: Charging Alternatives, as it may overheat, or damage to one or more of the solar panels could occur.
Owner’s Manual | Model A704-5 Aviation Lighting System Model A704-5 AC/DC Charger (Part# 48898) The A704-5 AC/DC charger consists of an AC adapter with a cable that plugs into the A704-5, and a power cord that connects the AC adapter to a North-American wall outlet.
Before contacting Carmanah’s customer service department, please have the serial number of your A704-5 available, a brief description of the problem, as well as all details of the installation and recharging efforts.
(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by Carmanah Technologies Corporation could void your authority to operate the equipment.
The chemistry of the batteries creates a small electrical current within them, and the electronics of the A704-5 will draw an even smaller amount of electricity to keep itself ready for use. The self- discharge is extremely low compared to the electrical currents when the A704-5 is in operation, but over time it becomes significant enough to require the regular check and recharge intervals outlined in Table 9-1: Recharge Intervals.
Owner’s Manual | Model A704-5 Aviation Lighting System Appendix B: Model A704-5 Battery Replacement The following instructions describe the proper method for replacing the Model A704-5 batteries. For the safety of personnel performing the replacement, ensure all the steps are properly followed.
