BATTERY RECHARGING
Rechargeable nicad batteries may take as many as 1,000
recharges, however they do have some limitations you should
be aware of:
1. Nicads will last only about half as long as
standard carbon-zinc batteries before
recharging is required.
2. Nicads may develop a “memory” if you give
them repeated “booster” charges. In other
words, if you charge your batteries over and
over again for only three hours at a time, the
BATTERY REPLACEMENT
1. Two drop-in battery packs are located in the
battery housing below the armrest. Each pack
contains four 1.5 volt AA batteries.
2. Remove the battery end cap by partially
unscrewing the knob on the battery end cap.
3. Remove the battery packs and replace the
batteries. Make sure the batteries are oriented
correctly as indicated by the polarity marks on
the inside of the packs.
4. Reinstall the battery packs, connector end first.
Note that the large split connector with the
spring behind it is the negative terminal and the
smaller terminal is the positive terminal. Both
should match up with the polarity markings on
the battery end cap. Another way to tell if the
packs are in correctly is by checking the position
of the rivets on the back end of the packs: the
rivets should always be facing in towards the
center of the battery housing.
5. Put the battery end cap back on and lock it in
place by tightening the knob, finger tight only.
NOTE: If either or both of the battery packs are installed
incorrectly, the 1266-X will simply not turn on. The instrument
will not be damaged.
