4-2. RECEIVE

4-2-1. Microprocessor back-up battery

The R-5000 has a rechargeable back-up battery which is charged automatically while the AC power cable is connected to an AC outlet. It takes about 6 hours to recharge a deeply discharged battery using the AC power cable. If you suspect the battery is not charged when you purchase the R-5000 or the radio performs erratically, perform the "A = B (reset)" procedure described in section 4-2-2. The battery will last about 10 days with the AC power cable disconnected.

4-2-2. Microprocessor reset

When the microprocessor has functioned erroneously or when installing the transceiver, switch on the power with the A = B key pressed.

Note:

The microprocessor can be easily reset. However, only perform this operation when necessary since the contents of the operated programmed memory are cleared by reset- ting. It can take a little while to reprogram 100 memory channels!

4-2-3. Beep tones

Audible confirmation of microprocessor functions is provided in the form of a series of audio beeps.

1.Preset the controls as shown in the accompanying il- lustration.

2.Place the POWER switch ON.

3.The meter will illuminate and a frequency will appear in the display.

Notes:

1.If the M. CH indicator lights, press the VFO/M key to select VFO operation.
