Micro-14 (140-1175) Power Sources Faxback Doc. # 7778 You can power the recorder from any of the following sources: Non-rechargeable batteries Rechargeable nickel-cadmium batteries DC (vehicle battery) power AC power INSTALLING BATTERIES The recorder uses two AA batteries. If you want to use non-rechargeable batteries, we recommend alkaline batteries, such as Radio Shack Cat. No. 23-552. Or, you can use rechargeable nickel-cadmium batteries, such as Cat. No. 23-125. You must charge nickel-cadmium batteries before you can use them to power the recorder. First, install the batteries as described in this section. Then, see "Charging Nickel-Cadmium Batteries." Follow these steps to install batteries. 1. Remove the battery compartment cover by sliding it in the direction of the arrow. 2. Insert the batteries in the battery compartment, as indicated by the polarity markings (+ and -). 3. Replace the battery compartment cover. CHARGING NICKEL-CADMIUM BATTERIES WARNING: Do not try to charge alkaline or other non-rechargeable batteries. They might overheat and rupture or explode. With an optional AC or DC adapter, you can charge nickel-cadmium batteries. First, install the batteries in the recorder. See "Installing Batteries." CAUTIONS: Connect an adapter to the recorder only when the adapter is connected to AC or DC power. Otherwise, the adapter drains power form the batteries. Occasionally, fully discharge nickel-cadmium batteries before recharging them. Otherwise, the length of time they hold a charge begins to shorten. The recommended adapters supply 3 volts with the center tip set to positive, deliver the 145 milliamps the recorder draws, and have plugs that correctly fit the recorder's DC 3V jack. Using an adapter that does not meet these specifications could seriously damage the recorder or the adapter. Charging Nickel-Cadmium Batteries Using AC Power Use an AC adapter, such as Cat. No. 273-1435A, to charge nickel-cadmium batteries with AC power. 1. Insert the adapter's sub-mini plug into the recorder's DC 3V jack. 2. Insert the adapter's other plug into a standard AC outlet. It takes about 10 hours to fully charge the batteries. (Charging time is longer if you operate the recorder while charging the batteries.). 3. When the batteries are fully charged, unplug the adapter from the AC outlet. Then, unplug the adapter from the he recorder. Charging Nickel-Cadmium Batteries Using DC Power Use a DC adapter, such as Cat. No. 270-1560, to charge nickel-cadmium batteries using your vehicle's battery power. CAUTIONS: Always plug the adapter into the recorder before plugging it into the cigarette-lighter socket. Always unplug the adapter from the cigarette-lighter socket before unplugging it from the recorder. Your vehicle must have a 12 volt DC, negative ground electrical system. 1. Set the adapter's voltage switch to 3V. 2. Insert the sub-mini plug into the adapter's socket. Line up TIP on the plug with +POS on the socket. 3. Insert the sub-mini plug's other end into the recorder's DC 3V jack. 4. Insert the adapter's large plug into the vehicle's cigarette-lighter socket. It takes about 10 hours to fully charge the batteries. (Charging time is longer if your operate the recorder while charging the batteries.) 5. When the batteries are fully charged, unplug the adapter from the cigarette-lighter socket. Then, unplug the adapter form the recorder. CHECKING BATTERY POWER If the REC/BATT indicator does not light or lights dimly when you press RECORD, it is time to replace or recharge the batteries. CAUTION: Press RECORD only when a cassette tape is loaded. Do not force down RECORD. USING AC POWER You can use an AC adapter, such as Cat. No. 273-1435A, to power the recorder with standard AC power. CAUTION: The recommended adapter supplies 3 volts with the center tip set to positive, delivers the 145 milliamps the recorder draws, and has a plug that correctly fits the recorder's DC 3V jack. Using an adapter that does not meet these specifications could seriously damage the recorder or the adapter. Follow these steps to power the recorder with AC power. WARNING: Remove alkaline or other non-chargeable batteries from the recorder before you connect the adapter to the recorder. Otherwise, the batteries might overhead and rupture or explode. 1. Insert the adapter's sub-mini plug into the recorder's DC 3V jack. 2. Insert the adapter's other plug into a standard AC outlet. USING DC POWER Using a DC adapter, such as Cat.
