The battery pack cannot be charged or battery power
depletes immediately after charging.
• Is the battery pack being charged with a charger specified by Yaesu?
Charge the battery pack using the accessory battery charger (SAD-20B/
C/U/G) or the rapid charge cradle (SBH-22).
• Is the battery pack in use exhausted?
If the “Charging Error” appears on the desktop charger lamp when
charging, there is a chance the battery pack is over discharged. If the er-
ror is repeatedly displayed after charging the battery pack several times,
the battery pack may have reached its service life or be defective. Battery
packs are consumables. Please replace an exhausted battery pack with
a new one immediately. Battery packs can be charged and reused up to
approximately 300 times.
Some specific combinations of signals may cause internal beats (“birdies”)
from high frequencies, caused by the internal oscillator. This is not a mal-
function.
(See the calculation formula below: “n” is for the arbitrary integer). Also, de-
pending on the combination of simultaneously received signals, there may
be fluctuations in receive sensitivity.
• Receive Frequency = 13 MHz × n multiplicative
• Receive Frequency = 19.2 MHz × n multiplicative
