WC1 panels has been completely exhausted. Partial stock of the WC2 panels is still
available, but difficult to locate. It should be noted that each model has superficially
different button panels (e.g. different branding), but all panels are interchangeable
between the 9Z models. This has led to many early 9Z’s and 9ZHP’s being ‘re-branded’
by the fitting of 9ZAP WC2 panels.
If you can find stock, replacement of the panels is simple:
1.
Purchase the required panels (see APPENDIX C for part numbers)
2.
Lever up the old panels with an old credit card or other hard plastic card that has
been ‘sharpened’ so that it can slip under the panel and break the initial seal. You
can use a knife to start things off, but be very careful as you can easily scratch the
9Z case. For this reason, do not be tempted to use a screwdriver.
3.
After removing the self adhesive panels glue residue will be left on the 9Z case.
Carefully remove all this residue by rubbing with your finger and then clean the area
with a damp soapy cloth. Finally, wipe over to remove any soap residue with a clean
damp cloth.
4.
After everything has thoroughly dried, peel the backing from the new button panels
and apply them to the 9Z case.
3.6. 35MHz Aerial Replacement and Servicing
Note: I have not replaced the Aerial so this procedure may be incomplete.
Warning: Always do a range test after replacing or servicing the aerial. If for some
reason you lose RF range after changing the aerial, then it is likely that this spring clip
has become dislodged. If this is the case then you’ll need to remove the transmitter case
top to gain access to the clip. To do this you will need to disassemble the case to Stage
3 (see Section 5) and then completely remove the bolts shown in Figure 57 on page 61.
The 35MHz aerial that comes with the 9Z cannot be removed for servicing without some
disassembly of the transmitter. However, this disassembly is trivial in most cases and
simply requires removal of the battery pack if you are careful. It is retained in the case by
an Allen key style bolt at its base and the electrical contact for RF transmission is made
by a spring clip in the ‘ball joint’ at the top of the transmitter case (see Figure 22).
