Power
This is a battery-powered instrument with the option of using a battery eliminator.
The power control is a momentary "ON/OFF" key located on the top panel.
For optimum battery life, turn the instrument off when not in use, or use the battery
eliminator.
In addition, from the UTILITY MENU, you can preset a time interval to automatically
turn off the instrument after the last key has been pressed. The display flashes to indicate
a low battery condition when both batteries are low.
For battery replacement, the battery compartment is located on the bottom side of the
instrument. To access, twist the slotted latch one-quarter turn and lift. Fit a coin into the
slot for increased leverage. Replace both batteries at the same time with two 9-volt
alkaline batteries: Duracell MN1604 or equivalent.
Note
Do not use mercury, air, or carbon-zinc batteries.
