This appendix provides solutions to common program and operation issues.
Do this ...
❑
Check the wiring to the battery. The red wire of the HTR1 power harness
should be connected to the positive battery terminal through a 3A fuse.
The black wire of the HTR1 power harness should be connected to the
negative battery terminal.
❑
Check the fuse. If the fuse is blown, determine the cause and rectify it
before replacing the fuse. Check for pinched or crossed wiring.
❑
Ensure that the DB25 connector on the HTR1 wiring harness is plugged
into the VCR.
❑
Ensure that the white wire of the HTR1 signal harness is connected to
the ignition switch and the ignition switch is on.
If the VCR powers up when you press the POWER button (temporary
power), the ignition switch connection may be faulty.
❑
Start the vehicle engine to make sure the battery voltage is high enough
to power the HTR1; that is, more than 10 volts.
❑
Ensure that the power, video, and audio connectors of the camera
harness are plugged into the HTR1 power, video in, and audio in jacks.
Make sure that the camera LED indicator is on.
❑
Start the vehicle engine to make sure the battery voltage is high enough
to power the HTR1.
❑
Ensure that the video tape is not write protected.
❑
Ensure that the vehicle is on, and that there is no Start Delay
programmed.
❑
Check to see if:
•
The tape is too old or worn; in either case the VCR cannot record to
the tape. We recommend that you do not use a tape more than 10
to 20 times, depending on how dusty or rough the roads may be
where the system is being used. The worse the operating
conditions, the more often the tapes should be recycled.
❑
•
The temperature is too cold; that is, lower than the recommended
operating range of +41ºF to +104ºF (+5ºC to +40ºC). You can
program the built-in timers to delay recording 10 to 20 minutes after
the bus is first started to give the VCR a chance to warm up as the
bus warms up (see
