2. Bend the leg of the diode as shown in the fi gure.
3. Solder the diode between Q61 (Collector) and the solder
pad (Base) of the Control unit (A/3), as shown in the fi g-
ure.
Note:
1) Confi rm the direction of the cathode band when install-
ing the diode.
2) Install the diode so that it is positioned on the dotted
line.
3) Install the diode so that its height from the surface of the
PCB is 4mm (0.16 inches) or less (Height of rubber sheet
(G11-4536-04): 4mm (0.16 inches)).
Install the diode so that it is positioned
on the dotted line.

Precautions for Reassembly
Perform the following steps when assembling the bottom
side of the transceiver.
1. Separate the two coaxial cables (E37-1495-05, E37-1496-
05) as shown in the fi gure.
2. Push the two fl at cables (E37-1491-05, E37-1492-05) into
the gap of the chassis so they do not come into contact
with the cabinet.

Caution for Replacing the LED
(B30-2322-05, B30-2323-05)
When replacing the “B30-2322-05” or “B30-2323-05”
LED used by the Display unit (A/6), order and replace the
LED for service into which the rank is divided according to
brightness, according to the following procedures, so that
the brightness of the LED backlight remains uniform after
replacing the LED.
1. Confi rm whether the “A” or “Z” stamp is pushed on the
foil side of Display unit (A/6).
Confirm whether stamp
“A” is pushed.
Confirm whether stamp
“Z” is pushed.
