Precautions for Reassembly
■Procedure when the packing (G53-0838-13) is
removed from the Panel ASSY
When the packing is removed from panel ASSY, affix
new sheet (G11-4376-04) to the panel ASSY by following
procedures.
1. Remove the white covering paper from the short side of
the sheet z.
2. Place the sheet on the edge of the panel ASSY x, then
affix it to one side of panel ASSY while pulling the right
and left sides of the transparent covering paper to make a
smooth contact (with no wrinkles) c.
Firmly affix the sheet to the panel ASSY by pushing the
double-coated tape with your fingers.
3. Remove the white covering paper from the other side of
the sheet v, then affix it to the other side of panel ASSY
b.
Note:
Affix it while pulling the right and left sides of the
transparent covering paper to make a smooth contact
(with no wrinkles).
Firmly affix the sheet to the panel ASSY by pushing the
double-coated tape with your fingers.
4. Remove the transparent covering paper from the panel
ASSY n.

■Affixing the cushion (G13-2129-14): KCH-14 only
Affix the cushion to the PC board along two through-hole
on the display unit (X54-349 B/3).
Speaker packing convex
(drain hole part)
DISASSEMBLY FOR REPAIR
■Fitting the convex (drain hole part) of the
speaker packing to the hollow (drain hole part)
of the panel ASSY: KCH-14 only
Push the convex (drain hole part) of the speaker packing
with a flat-head screwdriver as shown in figure until drain
hole of the speaker fit to the drain hole of the panel.

1. Display Unit
The optional display unit (front panel unit) for the TK-
5710(B)/5710H(B) comes in two models : KCH-14 and KCH-

1-1. KCH-14
This display unit consists of the CPU (IC3), 5V AVR (IC1)
and other components.
•Encoder
Channels are changed by the rotary encoder (ENC). The
up/down pulses from the rotary encoder enter the CPU
(IC3), and converted to a serial data signal, and are sent to
the control unit.
•Power supply
Power is supplied to the CPU by converting SB from the
control unit to 5V by IC1. And SB is supplied to the LED for
backlight.
