DIAL CORD RESTRINGING.
Refer to figure 5 and proceed
as follows:
a) Remove front panel by pulling off TUNING knob and
removing two Phillips-head screws.
b) Connect dial cord at drum hook marked START in
diagram.
c) String dial around nylon pulleys and tuning shafe to
drum hook marked FINISH in diagram. Make certain cord
winds around tuning shaft from rear toward front, as shown.
d) Attach end of cord with tension spring, making certain
that spring applies enough pressure to prevent cord from
slipping.
e) Tune in a known station and attach dial pointer at proper
position. Before securing pointer, twist cord as shown in
diagram so cord will exert a slight pressure toward panel
bracket and away from dial glass.
