Testing and Replacing the Battery
To Test Battery Strength:
With the unit on, press the battery test button (see
diagram on page 3), located at bottm of the front of
the unit - this will indicate the battery strength and
determine if it needs replacement. When the button
is pressed (with unit on) and light does not glow, it
is time to change the battery. Test the battery light
every few weeks.
To Replace the Battery:
The battery door can be removed by twisting a coin or similar object in the slot
provided. Check and replace the battery first if you experience any problems in
the operation of the DNS OTC. Use only Alkaline or Heavy Duty batteries.
Note:
Rechargeable batteries should
not
be used. Remove the battery if not
using the device for some time. Battery must be disposed of in line with the
local Environmental Protection Agency for requirements.
