Precautions for Reassembly

Procedure when the packing (G53-0838-13) is

removed from the Panel ASSYWhen the packing is removed from panel ASSY, affixnew sheet (G11-4376-04) to the panel ASSY by followingprocedures.

1. Remove the white covering paper from the short side ofthe sheet z.

2. Place the sheet on the edge of the panel ASSY x, thenaffix it to one side of panel ASSY while pulling the rightand left sides of the transparent covering paper to make asmooth contact (with no wrinkles) c.Firmly affix the sheet to the panel ASSY by pushing thedouble-coated tape with your fingers.

3. Remove the white covering paper from the other side ofthe sheet v, then affix it to the other side of panel ASSYb.

Note:Affix it while pulling the right and left sides of thetransparent covering paper to make a smooth contact(with no wrinkles).Firmly affix the sheet to the panel ASSY by pushing thedouble-coated tape with your fingers.

4. Remove the transparent covering paper from the panelASSY n.

Affixing the cushion (G13-2129-14): KCH-14 onlyAffix the cushion to the PC board along two through-holeon the display unit (X54-349 B/3).

Speaker packing convex(drain hole part)


Fitting the convex (drain hole part) of the

speaker packing to the hollow (drain hole part)

of the panel ASSY: KCH-14 onlyPush the convex (drain hole part) of the speaker packingwith a flat-head screwdriver as shown in figure until drainhole of the speaker fit to the drain hole of the panel.

1. Display UnitThe optional display unit (front panel unit) for the TK-

5710(B)/5710H(B) comes in two models : KCH-14 and KCH-15

1-1. KCH-14This display unit consists of the CPU (IC3), 5V AVR (IC1)

and other components.

• EncoderChannels 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 tothe control unit.

• Power supplyPower is supplied to the CPU by converting SB from the

control unit to 5V by IC1. And SB is supplied to the LED forbacklight.
