WARNING
Before disposing of used lithium batteries, insulate by affixing tape to the positive and
negative terminals or by other means. Otherwise, short-circuiting may occur, resulting in
heat generation, bursting or ignition.
On this equipment, lithium batteries is used for:
BT1 in the CPU control circuit (PC4401) (Maxell ER3)
Checking and Replacing the Battery
• The JMA-7700 series radar stores the tracks, marks, waypoints, and other settings in its internal lithium
memory. These items of information sre lost when the internal battery is exhausted.
• Checking the Battery

life of the battery is nearing its end, check its output voltage. Replace the battery if it reads lower than
3.0 volts.
• Battery replacement procedure
Replace the battery BT1 in the CMC-1055B CPU circuit board.
Be careful for making short-circuit between the battrey terminal.
The data on the memory is sustained by super-capacitance for a short period of time.
●
Do not keep used lithium batteries but dispose of them immediately after as non-combustible waste.
