Warning!
Repairs attempted with incorrect equipment
or by untrained personnel may result in
permanent damage.
Caution: CMOS devices
This equipment contains CMOS devices,
which are susceptible to damage from static
charges. Care when handling these devices is
essential. For correct handling procedures,
refer to manufacturers' data books covering
CMOS devices, such as Philips Data Handbook
Covering CMOS Devices or Motorola CMOS
Data Book Section 5 (Handling Procedures).
Screw head types
Torx recess head screws and Pozidriv recess
head screws require the correct sized driver to
achieve best performance. Most of the screws
in Tait Orca 5000 portable radios are Torx
head screws, and so a Torx T6 driver bit is
supplied as part of the service kit. Some earlier
radios have Pozidriv screws.
