ATTENTION
The battery for your GX660 has been factory installed. Caution
should be exercised opening the battery compartment as the
water tight integrity of the radio could be compromised if not
properly assembled. Applying a thin coat of organic vegetable
oil to the 0-ring may assist in assembly.
MAINTENANCE AND CAUTION
The GX660 is designed to provide years of trouble free
operation with virtually no maintenance. Follow these simple
procedures to ensure that the GX660 continues to deliver top
performance:
• Rinse the GX660 lightly with fresh water after exposure to
salt water or the radio’s keys may become inoperable due
to salt crystallisation.
• BE CAREFUL! Extreme shock (dropping, etc.) may crack
the case or dislodge or damage the seals. Additionally,
wear or improper battery pack installation can damage the
battery compartment seal.
• Never transmit without an antenna attached to avoid any
damage to the radio.
• Avoid using or placing the GX660 in areas with
temperature below -15°C or above + 55°C. Do not place
on windshields, etc.
