IMPACT MK2 Hand Held UHF Paging Transmitter
Battery Capacity
The batteries are 1.6Ah Nickel Metal Hydride cells. The number of hours operation on a
full charge is totally dependant upon the type of use to which the unit is put.
Transmissions use by far the greatest power, but with test calls set at 1 hour, the cells
should last several days between charges. Turning off the unit between use is
recommended, but it should be noted that long periods of no use will still reduce the
battery charge.
The battery indicator on the display will show the approximate capacity left in the cells.
At a preset point the unit will transmit a "Battery Low" message, flash the display
backlight and beep (if selected). When the battery voltage falls below that required to
run the transmitter, the unit will flash the display and the battery icon, then it will
automatically switch itself off, since it cannot perform its intended function without a
transmitter. It will then need recharging before it can be used again.
