6. In order to use the wireless microphone (RMT), an antenna must be
attached to the DVM. The DVM ships with a small “rubber duck”
antenna attached to the left side. An external roof antenna is also
included to enable greater transmission range, if needed. Please note that
the rubber antenna must be removed in order to install the external roof
antenna onto the DVM. If using the external antenna, please mount it
forward of any light bar on the roof of the vehicle for a clear line-of-sight
to the RMT.
Important: When installing the external antenna, do NOT use a
wrench to tighten the cable to the mirror. This connection should only
be finger tight. Over tightening the connection can potentially cause
damage to the connector inside the DVM.
The RMT must be within three feet of the rubber or external
antenna during the synchronization process.
Refer to the section
“Synching Wireless Microphone to the DVM” (page 5) for the procedure
on synchronizing the RMT to the DVM prior to recording videos.
7. Attach the GPS antenna to the rear of the DVM. This antenna can be
mounted on the dash or magnetically attached to the roof to receive GPS
signals. Signal reception can be verified by enabling the GPS display
text; please refer to Display Text Menu (page 21) for this option.
