Battery Model & Battery Compartment
The battery used in the ProMark 800 is a 7.4-V DC - 4600
mAh rechargeable battery. It is a standard model used in
many camcorders.
The battery is housed in a battery compartment accessible
from underneath the ProMark 800. The compartment door
can be removed using a coin to release the two quarter-turn
screws.
DC Power Input
A three-contact, female connector (Fischer type) allowing the
ProMark 800 to be powered from either the provided AC
adapter (connect the cable extension between ProMark 800
and the end of the AC adapter output cable), or an external
9- to 28-V DC battery through cable P/N 730477 (cf. base
configuration with radio).
GSM Antenna
A coaxial female connector (SMA type) allowing you to
connect a GSM whip antenna to the ProMark 800.
Radio Antenna
A coaxial female connector (TNC type) allowing you to
connect a radio whip antenna to the ProMark 800. This
connector is available only if the ProMark 800 has been fitted
with a radio module.
Radio Module
A module allowing ProMark 800 to receive and process
corrections from a base. When a radio module is used, a radio
antenna must be connected (see above). When no radio
receiver kit is delivered, a single compartment door is
provided instead, with no connector on it.
