Installing the Antenna
The antenna is an essential part of your VHF
725 and the unit should never be operated
without the antenna installed, as this may result
in damage to the unit. The antenna receives
signals best when held upright and is less effective
when positioned horizontally.
To install the antenna:
1. Carefully align the bottom of the antenna with the
threaded connector on the top of the VHF 725, and
screw it on the until snug against the seating
surface. (Figure 1)
Installing the Battery Pack
The VHF 725 uses a rechargeable NiCad
Battery Pack to provide approximately 10 hours of
operating time under normal use. Alkaline “AA”
batteries installed in the optional GARMIN
Battery Tray may also be used. The battery level
indicator at the lower left corner of the unit LCD
display gives indication of battery capacity in
increments of 25%. The Battery Pack is provided
with a Charging Stand and Charging Unit.
To assemble the Charging Unit:
1. Insert the Charging Unit cord plug with contact
pins into the base of the Charging Stand. Position
the flange on the plug over the slots in the bottom
of the stand base and then press down until it
clicks into place. Pull the cord away from the stand
slightly to allow the plug to move down freely.
(Figure 2)
2. Connect the Charging Unit to a 120 VAC Power
Outlet.
3. The NiCad Battery Pack should be installed in
the VHF 725 when you remove it from the shipping
carton. Place it base-down into the charging stand
and allow 12 hours for charging to full capacity.
