What to do if there is no sound from the Furuno Telephone loudspeaker?
If you have power but no sound from the loudspeaker, ensure the [SPEAKER] key is on. If "SQ" appears on the display, press the [SQ] key. Also, the volume may be too low, so adjust the VOLUME control. Finally, check the RF Gain control and turn it clockwise.
How to fix Furuno FS-1562-15 Telephone when power can not be turned on?
If the Furuno Telephone won't power on, first check if the mains switchboard is on. Then, check the supply voltage to ensure it's less than 31.2V. Also, recharge the battery and tighten the terminal connections. Replace any blown fuses.
What to do if Furuno Telephone antenna coupler can’t tune antenna?
If the antenna coupler can't tune the antenna, check the antenna connection and ensure the recommended length is 7 to 30 meters. Verify the coupler ground and check the mains voltage and polarity. If normal, reset the breaker. Also, inspect the connection cable.
Why is the articulation poor on my Furuno FS-1562-15 Telephone?
Poor articulation can occur if the wrong class of emission is in use, or if the receiver is detuned. Select the same class of emission as that of the incoming signal. In Custom or ITU channel mode, press the [CLARIFY] key then fine tune frequency by the FREQ/CH control.
How to tune in a broadcast station on Furuno Telephone?
To tune in a broadcast station, ensure you include the last numeral at the digit of 1. For example, to tune to 9640 kHz, press [RX], [9], [6], [4], [0], [0], [ENT]. Select H3E. If you still can’t tune in, try another frequency.
What to do if output power is low on Furuno FS-1562-15?
If the output power is reduced to low and the "LOW" indication blinks, the power is automatically reduced to protect against overheating due to continuous transmission. Wait until the unit returns to normal condition.
What to do if key input is not accepted on Furuno FS-1562-15?
If key input is not accepted, the FS-1562 may be under the control of external equipment. Suspend operation of external equipment.
What to do if frequency readout appears but no lamps light on Furuno FS-1562-15?
If the frequency readout appears but no lamps light, the [DIMMER] key may be off. Operate the [DIMMER] key.
