-Bravo Express Self-Diagnostics-
With the pager off, Hold the Select ( ! ) button, then hold the Mode (^)
button, then press and hold the READ button. Then release all buttons at
once. The display will say "POCSAG 0x", x=software version number. The
receiver is now set to track 1, the battery saver is disabled, and the
pager is now in "quick page" mode. While in Quick Page mode, a function 3
page (whatever that is) will now cause the pager to emit a short beep.
Pressing the Mode button will enter SPL test, a continuous tone will be
heard. Pressing the Mode button will return to Quick Page mode. To exit
self-test mode, press the read button.
--------------------------------------------------------
-Bravo (golay and pocsag version) Self Diagnostic feature-
Hold the read (^) button and the protect button (with a picture of a
padlock), and turn the pager on. Release both buttons. You will now hear a
continuous tone and "SPL" will appear on the display for the English
version, or --1-- on the international version. Within two seconds, press
the read button to enter self-diagnostic mode or the protect button to
enter the code-plug reading mode. In pager sensitivity test, the battery
saver is off. A short beep will be heard when a page is received instead
of the normal, longer one, and the display will read "paging" (--2-- in
the international). pressing read will enter the lcd test, which can be
controlled by the protect button but will proceed without any operator
intervention. Press the read button to go on to the code plug reading
test. Either a the first CAP-code or "CHEC FAIL" will be displayed. Chec
fail means a bad code plug or illegal CAP-code ( in the international
version, chec fail is indicated by a "checkerboard" pattern). The read
button exits this routine, or, within 5 seconds press the protect button
for reading the second CAP-code. Pressing the protect button here will
cause the option codes (described next) to be displayed in hexadecimal,
otherwise, letting this step time out will cause them to be display in
binary. OPTIONS: from left to right on screen GSC (Golay) options:
page 1: 0=battery saver, 1=chirp, 1=short alert (a hidden option),
1=manual reset, 1=beep on bad data (a hidden option), 0=dead man timeout
alert (not a user feature), 1=data invert, 1=English displays page 2:
1=2 codes active, 1=word 1a equals word 1b (not a user feature),
1=individual code 2, 1=tone and data rather than all data, 1= unique code
2 alert as opposed to 4 function alerts, 1=silent code 2, sequential
lockout (00=none,01=64 sec, 10=2.7 min, 11=6.4 min) page 3: xxxx=code 1
priority override option bits order4 3 2 1, code 2 priority override
option bits order 4 3 2 1 If Hex display selected, pages are displayed in
bytes starting at left of screen...on right is "d" for defeat reminder
active. finally, in hex, 4 bit preamble index (1101 is used when no
battery saver), 8 bit word 1, 12 bit word 2, 4 bits of functions active
(in order of 4 3 2 1) POCSAG options: page 1: 1=data invert, alerts on
code 2 (00=silent, 01=unique alert, 10=4 function alerts), 1=english
displays, sequential lockout (00=none, 01=64 sec, 10=2.7 min, 11=6.4 min),
1=chirp, 1=ground call 2nd code page 2: bits 1,3,4,5 are code 1 priority
override option bits, in order 1 2 3 4. bit 2 is individual code 2
(1=active). bit 6=out of range indicator, bit 7=beep on bad data, bit
8=manual reset page 3: bits 1,2,3,4=code 2 priority over-ride, order
1 2 3 4. bits 5 6 7 8=active code 2 functions, order 4 3 2 1 If Hex
display mode enabled, page one is leftmost byte. "P" in 2nd to rightmost
position means international character set is selected, "d" in rightmost
position means reminder defeat is active. After the options display is
the switch test, press read to enter. LCD will display "Controls"
(--3-- on international), there will be a "checkerboard" character on
each side of a single digit indicating which button has been pushed,
1=protect, 2=on-to-memo-alert, 3=memo-alert-to-on. If there is a
vibrator in the unit, pressing read will display "vibrator" (--4--
international) and unit will vibrate while display is lit. pressing
either button will exit this step. Pressing read will re-enter the
self-diagnostic mode. To exit self-diag, press read then press protect,
and pager will return to normal. In POCSAG, the out of range indicator
will appear when pager has not received a signal for 6 minutes. Here is
my attempt to suggest what this looks like:
_ _ _ _ _ _ | |_| |_| |_ | |_| |_| |
As soon as a signal is re-acquired, the display will return to normal.
