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

Eight 1.5V size AA batteries are located in the rear section of

the Control Housing. The batteries are sealed off from the

electronics so that accidental water leakage into the battery

compartment will not damage the circuitry.

1. Remove the battery cover by partially

unscrewing the two knurled thumb screws with a

coin. (The knurled knobs are “captive screws” and

do not have to be completely removed from the

battery cover.)

2. Remove the battery pack from the Control

Housing and disconnect the battery lead

connector. Be very careful not to put any undue

strain on the battery leads.

3. Remove the batteries from the battery packs.

Note the polarity markings inside the pack and

install fresh batteries.

4. Reconnect the battery lead.

5. Insert the battery pack into the Control Housing

with the lead connector up, on the right side. Fold

the leads across the top of the pack.

6. Make sure the O-Ring and both sealing surfaces

are clean before reinstalling the battery cover. THIS

IS EXTREMELY IMPORTANT.

7. Finger tighten the thumb screws, then carefully

tighten again one-quarter turn with a coin.
