Use of Heat Sink
VT15 Series Transmitters operating at or above 500 mW require the use of a heat sink or
must be securely fastened to an adequate heat sinking object or surface. AMP Heat Sink
VH1205 (1.25” wide by 0.58” high) is recommended for 500 mW and 1 Watt models
while VH2505 (2.56” wide by 0.50” high) is recommended for 2 Watt models. VT15
transmitters should be fastened to AMP heat sinks using provided 4-40x5/16” pan head
or socket head screws with #4 lock washers. Use of thermal grease, such as Wakefield
Engineering 120 Series Thermal Compound, to improve thermal conduction between
transmitter baseplate and heat sinking surface will reduce unit temperature and increase
product reliability.
4.4
Initial Adjustments and Settings
There are no initial adjustments or settings necessary to use AMP Transmitters other than
proper configuration of the slide switches as outlined above in Section 4.2. To assure
optimum performance, the user should be familiar with the camera, monitor, microphone,
and speaker/headphones used with this video/audio system.
4.5 Shut
Down
If the transmitter is to be shut down only briefly, simply remove DC voltage from the DC
Power Cable or disconnect DC Power Cable from transmitter. If the unit is to be shut
down for an extended period, all external cabling including the antenna should be
removed and the unit should be stored in a container and placed in a clean, dry
environment.
5.0 MAINTENANCE
INSTRUCTIONS
5.1 Cleaning
AMP Transmitters should be periodically wiped off with a clean, damp cloth. For more
thorough cleaning, dampen a clean cloth with glass cleaner and wipe off unit. Ensure
units are completely disconnected from their power sources before cleaning.
5.2 Troubleshooting
To avoid poor performance, ensure all transmitter and mating connectors are tightly
fastened, clean, and have no pins bent or damaged.
Verify configuration of all slide switches (refer to Section 4.2).
If poor or no operation is observed, ensure the external DC voltage supply is b9
and +16 Vdc with correct polarity. All AMP Transmitters have over-voltage and reverse
polarity protection circuits. If the input voltage is over +16 Vdc, remove the DC Power
Cable from the transmitter, reduce the DC voltage to b9 and +16 Vdc, and
reconnect the DC Power Cable. If the input voltage is negative polarity, remove the DC
Power Cable from the transmitter, reverse the connections between the DC voltage
supply and DC Power Cable, and reconnect the DC Power Cable.
If all connections are adequate, switches are correctly configured, and DC voltage is
correctly applied, check the video camera, video cable, and antenna for damage. A
monitor may be connected directly to the camera to verify proper camera operation.
