Troubleshooting

Storage:

     Store the VHF 725e in a cool, dry location when not used for
prolonged periods. When stored for more than six months, remove
alkaline batteries to prevent leakage from expended cells. While the
GARMIN VHF 725e is designed to withstand immersion in water
(with or without the battery pack in place) it should be treated like
all quality electronic equipment. Wipe away any water accumula-
tion from the surface of the unit and use a paper towel or other
absorbent material to wick out any moisture from the battery cavity.
Exposure of battery terminals to salt spray may cause corrosion and
loss of conductivity. Be certain to keep contacts dry and away from
corrosive elements. Storage temperature should not vary from:
below -4 degrees F (-20  degrees C) and  above 158 degrees F (70 C)

Cleaning:

     Clean exterior portions of the VHF 725e with a mild soap and
water solution. Do not use harsh detergents or solvent based
cleaning agents. Isopropyl alcohol is acceptable. Wipe dry with a
clean, non-abrasive cloth.

Battery Maintenance:

     Keep battery contacts clean. Use only the  NiCad Battery Pack or
types of batteries specified for use with VHF 725e. The VHF 725e
accepts six (6) standard “AA” alkaline, rechargeable alkaline or
rechargeable NiCad cells when the optional battery tray is used.

     It is advisable to maintain a supply of replacement batteries if the
VHF 725e is to be placed in service for a prolonged period where
recharging of the NiCad Battery Pack is not possible and replace-
ment batteries cannot be easily obtained.

NOTE: 

Whenever possible, transmit with 1 watt power to prolong battery

life.
