Advice when there is a problem

Caution
Check the following before requesting repair services.

There is no power

z Is the external power supply connected correctly?
Check the AC power supply; plug the connectors of the provided power supply cable all the way into the jacks.
Check the DC backup power supply; connect the black wire to the minus terminal and the red wire to the plus terminal.
z Is the voltage and current capacity of the external power supply sufficient?
Check the voltage and current capacity of the external power supply.
z Is the fuse open/blown?
Replace the fuse.

There is no sound

z Is the squelch level or setting too high?
Adjust the squelch level when receiving weak signals.
z Is the volume too low?
Increase the volume by turning the VOL knob in a clockwise direction.
z Is the tone squelch or DCS turned on?
When the tone squelch or DCS is turned on, no sound will be heard until signals containing the same tone frequency or DCS code as the repeater setting
are received.

There is no transmission

z Is the transmit frequency set to the amateur band?
Transmission outside the amateur band is not possible.
z Is the antenna or coaxial cable at fault?
Replace the antenna or coaxial cable.
z Is the voltage of the external power supply normal?
When the voltage of the power supply drops during transmission, the radio may not function correctly.
Use a stable power supply with a proper voltage and current capacity.

There is no screen on the display

z Is the screen timeout timer set to ON?
Press and hold the DISPLAY button for 3 seconds to turn on the display.
Set a longer period of time for the timeout timer in the setup mode.

About internal spurious signals

Due to the combination of oscillator signals produced at the same time in the receiver, there may be some internal heterodynes due to the high frequency of the
internal oscillator. However, this is not a malfunction (refer to the calculation formula below: n is any integer). Depending on the combination of the frequencies
received at the same time, there may also be fluctuations in the reception sensitivity.
z Reception frequency = 12.288 MHz x n times
z Reception frequency = 2.4576 MHz x n times
z Reception frequency = 11.1 MHz x n times
z Upper (Band A) frequency = (Lower (Band B) frequency ± 44.85 MHz) × n times
z Lower (Band B) frequency = (Upper (Band A) frequency ± 47.25 MHz) × n times @ Upper band (Band A) MODE = NFM

After-market Services

 The warranty period is 1 year from the date of purchase
The warranty certificate is enclosed with the product. Malfunction arising during normal use of the product in accordance with the instructions in the operating
manual, within a period of one year from the date of purchase, shall be repaired free-of-charge.
 Keep the warranty certificate in a safe location
When the warranty certificate is lost, failures which occur during the warranty period will be treated as chargeable non-warranty claims.
A warranty certificate where the necessary information such as the purchase date and the name of the retail store have not been filled in will also be treated
as void. Please ensure that the date of purchase and the name of the retail store are filled in correctly on the warranty certificate.
 You may also check with us for any non-warranty repairs
We will make repairs at your expense if the functions can be reliably maintained after the repairs. Please check with the retail store or Yaesu customer support
for more information.
 Save the packaging box
When sending this product for inspection and repair, use the original product packaging box to prevent shipping damages during the transport.
