VT30/OM Rev-A
10
When 100 kHz subcarrier frequency response is specified on either or both subcarriers,
the Audio Level switch for the corresponding subcarrier(s) is inactive and the 100 kHz
data is transmitted at a constant FM deviation sensitivity (no ALC).
4.3
Use of Heat Sink
VT30 Series Transmitters operating at or over 500 mW RF output power must utilize
AMP Heat Sink VH2505 (0.5” high) or be securely fastened to an adequate heat sinking
object or surface. VT30 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.
Caution: Failure to provide adequate heat sinking VOIDS PRODUCT
WARRANTY.
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).
