TROUBLESHOOTING
NOTES:
1) Try using a battery pack from a working radio. If the radio in question works with
that pack, the original battery is suspect. Charge the suspect battery as
recommended on page 7. If the charged original battery cannot power a JBX
handheld, charge it again with a different charger. If the battery still does not hold a
charge, replace it. If the battery appears to be "good" after using the second
charger, the first charger may be faulty.
NOTE: JOBCOM radio accessories come with a 90-day limited warranty. If an
accessory does not operate properly, contact your dealer or RITRON.
2) Reception can often be improved by moving the unit a short distance. This effect is
more noticeable inside buildings. The range of JBX portables equipped with a
standard battery pack is about two miles line-of-sight.
3) Adjusting the squelch for "threshold" allows the receiver to detect all except very
weak incoming radio signals.
4) If you want to call or hear someone who is using a "blue dot" JOBCOM handheld, for
example, you must use a blue dot radio. A color dot label attached to the case
indicates the radios frequency. Refer to the table on page 3.
5) Maximum power drain occurs while the radio transmits, so dont hold down the
Push-To-Talk button more than necessary. Battery power is used while the
handheld is left ON to receive calls. If practical, switch the unit OFF.
6) In extreme cold, a battery's charge capacity is greatly reduced. If you use the radio
in very cold weather, periodically warm the JBX portable underneath your coat if
possible. Using an optional remote speaker/ microphone allows keeping the radio
under your coat while transmitting and receiving.
7) A supervisor (or the appointed person n your group) will probably know which
radios are equipped with Quiet Call, and with which codes. The JBX portable may
be opened to check for a QC module, or to program a different code. The QC
module is located below the radio speaker, plugged into the 9-pin connector (FIG-3,
page 10).
TO PROGRAM THE QUIET CALL MODULE, REFER TO THE GUIDE PACKAGED WITH
THE RTS-5PA.
