Installing the Antenna
The antenna is an essential part of your VHF
720 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:
Installing the Battery Pack
The VHF 720 requires six AA alkaline cell
batteries and will provide approximately 19 hours
of operating time under normal use. Rechargeable
alkaline, NiCad batteries or the optional GARMIN
NiCad Battery Pack 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%. If NiCad rechargeable
batteries are used in the battery tray the battery
gauge measurement will not accurately indicate
battery capacity. However, the optional NiCad
Battery Pack will be accurately indicated.
To install the batteries:
