TroubleshootingStorage:

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.

NOTE: Whenever possible, transmit with 1 watt power to prolong battery life.
