APPENDIX D
Storage:
Store the VHF 725 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 725 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 accumulation
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 degrees C)
Cleaning:
Clean exterior portions of the VHF 725 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.
Submersion in Water:
The VHF 725 is constructed to meet IEC Standard 529 IPX7. It can
withstand submersion in 1 meter of water for up to 30 minutes. Note
that, while the unit is designed to operate after submersion, meaning;
if dropped in water and retrieved quickly, it should suffer no damage.
Prolonged submersion may cause damage to the unit. After submer-
sion, be certain to remove the battery pack and dry the battery
contacts and the battery cavity, as the battery cavity is separated from
the rest of the unit and can allow water intrusion.
Battery Maintenance:
Keep battery contacts clean. Use only the NiCad Battery Pack or
types of batteries specified for use with VHF 725. The VHF 725
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
725 is to be placed in service for a prolonged period where recharging
of the NiCad Battery Pack is not possible and replacement batteries
cannot be easily obtained.
Whenever possible, transmit with 1 watt power to prolong battery life.
