Select Battery Type

You have two choices: NiMH and Alkaline. The unit is shipped with the switch
in the Alkaline position. Use a pen or small screwdriver to select the battery
type.
CAUTION:
If you are using any battery type other than rechargeable Nickel
Metal Hydride (NiMH) batteries, make sure the BATTERY selection switch is in
the alkaline position.
WARNING
: Do not place the BATTERY switch in the NiMH position if you are not using Nickel Metal Hydride Batteries. The NiMH position
will attempt to charge any batteries in the unit, even if they are not the proper type. Charging non-Nickel Metal Hydride (NiMH) batteries
will result in physical harm, destruction of property and/or fire.

The SQ switch is inside the battery compartment next to the Battery Select switch. The unit is
shipped with SQ in the ON position. To turn it off, use a small screwdriver or pen to slide the switch to
the OFF position (to the right). See page 45 for more information on SQ.

Place two AA batteries in the compartment, making note of the battery polarity shown in the
