ecute the memory record function. The unit will not automatically turn itself off while in the

tery power voltage drift.
1. To adjust the contrast, remove the instrument from the rubber holster, and with your finger
roll the LCD Contract Adjust knob until the LCD display is easily read.
2. After adjusting, replace the unit back into the rubber holster for protection.

than 6.5V - 7.5V. It is necessary to replace the battery. When you see the LBT display, an in-spec

the instrument becomes inaccurate.

holster.
2. Pry the Battery Cover open with a coin or screwdriver
and remove the battery.
3. Replace with a 9V battery (heavy duty type) and re-
