Installing the batteries
For HC-4000/HC-4100 users:
Before starting to use the unit, you must install the main batteries as well as the
backup battery.
Caution:
• Use only AA (LR6) alkaline batteries or the optional Ni-MH Rechargeable Battery
Pack for the main batteries, and a CR2032 lithium battery for the backup
battery. Using other types of batteries may result in loss of data.
• Always have the main batteries installed before installing the backup battery.
1. Slide the battery replacement switch to the REPLACE MAIN BATTERIES
position. (When you release the switch, it may slip to the REPLACE BACKUP
BATTERY position. This is not a problem.)
2. Pull out the battery holder.
