Before returning any models to the customer, a safety check of the entire instrument should be made.
The service technician must be sure that no protective device built into the instrument by the manufacturer
has become defective or inadvertently degraded during servicing.
1. WARNING:
Alterations of the design or circuitry of these models should not be made.
Any design changes or additions such as, but not limited to, circuit modifications, auxiliary speaker
jacks, switches, grounding, active or passive circuitry, etc. may alter the safety characteristics of these
models and potentially create a hazardous situation for the user.
Any design alterations or additions will void the manufacturer’s warranty and will further relieve the
manufacturer of responsibility for personal injury or property damage resulting therefrom.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special characteristics. These characteristics
often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc. Replacement parts that have these
special safety characteristics are identified in this manual and its supplements; electrical components
having such features are identified by a
any of these components, read the parts list in this manual carefully. The use of substitute replacement
parts that do not have the same safety characteristics as specified in the parts list may create shock, fire
or other hazards.

ALIGNMENT PROCEDURE
Test Mode For Base Unit
Press the “ ” and “#” keys at the same time about 1.5 seconds while turning the power on, the confirmation beep
will sound to indicate that the unit is in the test mode.
1. To change the TEST mode: Press the number key for the corresponding TEST mode.
(Refer to the following table)
2. To change channel:Press the “RDL” key, but if changing the step, the channel returns to the start
channel.
3. To cancel Test mode:Bell rings, charge the Handset or Power off.

To perform the TEST mode, turn the power ON by pressing the “ ” and “#” buttons at the same time.
When entered the TEST mode, the bell rings and the unit enters TEST mode 1 . ( Refer to the following table. )
1. To change the TEST mode: Press the number key for the corresponding TEST mode.

2. To change channel:Press “CH” key.
( Note: If the step is changed, the channel returns to the start channel. )
3. To cancel the TEST mode:Turn the power OFF, charge the Handset, or press the “TALK” key.
*A : Squelch ON is H, or Squelch OFF is L.
*1 : In the TEST mode 3, “0000...” will be fed out continuously as transmitting data.
*2 : In the TEST mode 6, bell (1kHz) rings when the data received is “0000...”.
*3 : In the TEST mode 7, bell rings with initial 2 tone (2kHz, 2.2kHz).
*4 : In the TEST mode 8, bell (1kHz) rings when P_BATLOW is “L”.
*5 : In the TEST mode 9, bell rings when P_CHRGIN is “L”.
