of any accumulated moisture caused when
1145-2 Laser Transmitter passes through
(16) LOW VOLTAGE INDICATOR LAMP. A red
LED miniature warning lamp that flashes
when the 6-Vdc internal battery falls below
the safe operating voltage. The Low Voltage
Indicator Lamp stays on continuously when
transmitter is hooked to 12-Vdc external
battery, to warn that external battery has
discharged below safe operating voltage.
Laser beam automatically shuts off and
rotor pentamirror assembly stops rotating
when Low Voltage Indicator Lamp comes on.
At 60° F (16° C), battery operating time is
approximately 40 hours after battery has
been charged for 16 hours.
Do not connect the 1145-2 Laser Transmitter to a 24 Vdc charging system or damage to
equipment will result.
(17) POWER/CHARGER CONNECTOR. Receptacle for all external electrical connections. When control
switch is in OFF/Change position the internal battery charging circuit is activated. Internal
battery can be charged from the 110-/220-Vac Wall Outlet Charger or from a 12-Vdc external
vehicle battery. The 12-Vdc charging options allow you to charge the 6-Vdc internal battery from
your truck battery on remote job sites where AC electrical power is not readily available. Maximum
charge and longest battery life occurs when internal battery is charged frequently between 60° F
and 90° F (16° C and 32° C).
