A completely discharged instrument can be charged to full capacity
within 8 hours. Batteries drain slowly even if an instrument is off.
Therefore, if the instrument has been in storage or has not been

The factory-supplied battery is designed to last for 16 hours of normal
operation (no alarm), for a new battery under the optimum
circumstances. As the battery becomes older or is subject to adverse
conditions (such as cold ambient temperature), its capacity will be
significantly reduced.
Alkaline Battery Adapter
An alkaline battery adapter is supplied with each instrument. The
adapter (part number 059-3052-000) accepts four AA alkaline
batteries (use only Duracell MN1500) and provides approximately 12
hours of operation. The adapter is intended to be used in emergency
situations when there is no time to charge the Li-ion battery pack.
To insert batteries into the adapter:
1. Remove the three Philips-head screws to
open the compartment in the adapter.
2. Insert four fresh AA batteries as indicated
by the polarity (+/-) markings.
3. Replace the cover. Replace the three
screws.
To install the adapter in the instrument:
1. Remove the Li-ion battery pack from the instrument by

2. Replace it with the alkaline battery adapter
3. Slide the tab back into place to secure the battery adapter.
