to the cords are special inductive filters and are required to maintain compliance with FCC
requirements for conducted emissions. No attempt should be made by distributors or users to
fabricate replacement or alternate cables, to modify the length of these cables, or to remove or
change the filters on the cables.
NOTE
: The AC Adapter/Charger has been designed specifically for the OmniQuest
®
ST251.
Only this unit should be used to provide power to the MT for operation or to charge the
Battery Pack from an AC power source.
4.7.4 Standard Carrying Case
The Standard Carrying Case provides space to accommodate all of the standard components of
the OmniQuest
®
, and AC Adapter/Charger. Also provided with the Standard Carrying Case is a
magnetic compass and a Quick Reference Card to assist in setup. The Standard Carrying Case is
constructed of 600 denier nylon with reinforced seams.
NOTE
: The Standard Carrying Case only provides light protection to the OmniQuest
®
components from moisture and impact. The user is responsible for ensuring that the
OmniQuest
®
components are protected to a level consistent with the users specific
operating and transportation environment.

Cigarette Lighter Adapter (CLA)
The SZ601A Cigarette Lighter Adapter (CLA) provides a method to supply 9.6V DC input to the
MT from a standard 12V vehicle cigarette lighter socket. The CLA cables are similar in length
to the AC Adapter/Charger cables. The CLA is functionally equivalent to the AC
Adapter/Charger and can both power the OmniQuest
®
unit and charge a battery while installed in
the OmniQuest
®
unit or when installed on top of the charger.
NOTE
: The SZ601A CLA has been designed to meet the specific voltage requirements of the
OmniQuest
TM
ST251. Only the SZ601A should be used to provide power to the MT for
operation or to charge the SZ511A Battery Pack from a standard cigarette lighter
socket. Use of other CLA adapters may void the ST251 limited warranty.

OmniQuest
®
Junction Box
Only OmniQuest
®
specific Junction Boxes (SZ351A, SZ352A) are designed to work with the
ST251 terminal. Both Junction Boxes provide the capability of using the PTT Microphone and
allow the use of hands-free accessories (i.e. external speaker, microphone). The SZ352A
Junction Box includes a longer cable and is therefore more suitable for permanent vehicle
installations or if the customer desires a longer cable. The Junction Box connects to the “J-Box”
port of the OmniQuest
®
TU. For hands-free operation, the user connects the hands-free
microphone and speaker to the junction box.
NOTE:
Although the handset contains an external speaker which will provide hands-
free/dispatch audio, the external speaker is a desirable and highly recommended option
if the handset speaker is not loud enough or a remote location of the speaker is desired.
