2.7.1 Charging and Storing the Batteries

When you receive the PT900, you will need to initially charge the batteries. Also,
the batteries may need to be recharged if they have not been used for a long period
of time. The batteries must be charged for up to 3 hours to go from 0% (totally
depleted) to 100% (fully charged). When fully charged, the batteries provide
18-20 hours of continuous operation. An internal battery gauge indicates the
remaining power in the battery.
To charge the battery, simply plug the AC power adapter cord into the power jack
(see Figure 44 on page 34) and be sure the battery pack is installed in the
transmitter (see "Installing a Battery Pack in the Transmitter" on page 6). Whether
the PT900 is On or Off , when the AC power adapter is plugged into line voltage the
internal transmitter battery charger automatically charges the battery. The battery
LEDs (see Figure 49 below) indicate the battery charging status.
Figure 49: Battery Charging Status LEDs
For optimal run time, charge the batteries only in temperatures from 32°F to 113°F
(0°C to 45°C). Otherwise, the batteries will not be properly charged and will have
significantly reduced run time. Store the batteries at temperatures ranging from
-4°F to 122°F (-20°C to 50°C). The recommended storage temperature range is
-4°F to 77°F (-20°C to 25°C). Extended storage at temperatures above 104°F
(40°C) could degrade battery performance and service life.
