Recharging Nickel-Cadmium
Batteries
You can use a battery charger, Cat. No.
23-249 (not supplied), to charge or re-
charge nickel-cadmium batteries while
they are inside the TRC-237’s battery
compartment.
Do not use the TRC-237 while you are
charging the nickel-cadmium batteries.
Cautions:
• Use only the recommended battery
charger to recharge the batteries in
the TRC-237. Other chargers could
damage your TRC-237 or the batter-
ies.
• Be careful not to overcharge nickel-
cadmium batteries.
• To prevent damage to rechargeable
nickel-cadmium batteries, never
charge them in an area where the
temperature is above 90°F (32°C) or
below 40°F (4.5°C).
