Do not pull up the self-adjusting band when not
in use, as this will consume the battery power.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270°C
during repairing.
• Do not touch the soldering iron on the same conductor of
the circuit board (within 3 times).
• Be careful not to apply force on the conductor when
soldering

• H : adjustment for repair.
• Power voltage is dc 2.4V and fed with regulated dc power supply
from external power voltage jack.
•Voltages and waveforms are dc with respect to ground under nosignal (detuned) conditions.
•Voltages are taken with a VOM (Input impedance 10 MΩ).
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
• Signal path.
