when entering certain data through LCD menus. Being a
mechanical device, it is not uncommon for operations to
be occasionally missed and this does not represent a fault.
4. SQ - Squelch Control: The squelch control is used to
eliminate unwanted background noise when monitoring a
normally inactive frequency. Rotate the control clockwise
until background noise just disappears (threshold point),
this is the most sensitive setting of the control. In practice
the control is usually rotated a little further clockwise
beyond the threshold point to prevent the receiver from
stopping on noise or very weak signal.If the control is
rotated too far clockwise, B110RA can only open for very
strong signal and weaker signals will be totally lost.
5. VOL - Volume: When rotated fully clockwise the volume
is at maximum, when rotated fully anti-clockwise the
volume is reduced to minimum.
FRONT PANEL
6. LCD (Liquid Crystal Display): This is to display
frequencies, bank and or channel numbers receiving
mode, frequency increments and many more statuses of
B110RB. The lower left corner of the LCD displays a
legend “BUSY” to indicate that the squelch is opened. To
the right is the signal strength meter presented as a bar
graph. The stronger the signal then the larger the graph. It
is quite common for a few of the signal meter segments to
appear due to background band noise even when no
signal is present.
[PWR] - Power On/Off Key: To turn on the radio, press
power key and hold for more than 1.5 seconds. To turn off
the radio, press power key and hold for more than 1.5
seconds. The [PWR] switch is not of a common volume
control combined arrangement as a SLEEP timer can also
switch the receiver Off when programmed and
activated.The K.LOCK - key lock switch located on the left
side panel prevents accidental switch On and Off of the
receiver.
[SRCH] [S.PROG] - Search & Search Program Key:
When the [SRCH] key is first pressed the receiver initiates
search mode for one of the programmed search banks.
If no data is stored in the program search banks, the
receiver will not be able to search. When [SRCH] is
pressed a second time during search, the SEARCH
process is cancelled and the mode is returned to manual
mode where the frequency may be monitored or used as
the starting point for manual tuning. To return from
SEARCH to MANUAL mode and receive the originally
selected manual mode frequency, press [MANU].
The key sequence [2ndF] [SRCH] (short press of the
[SRCH] key) initiates the process for search banks
programming.
The key sequence [2ndF] ]SRCH] (long press of the
[SRCH] key for more than 1.5 seconds) initiates the
process for linking of search banks.
[SCAN] [BANK] - scan / memory recall / search bank
preview key.
When the [SCAN] key is pressed briefly, the receiver
enters MEMORY RECALL mode, the display legend
“BANK” appears on the top left of LCD with bank and
channel number. The B110RB monitors whatever
frequency is displayed on the LCD. The numeric keypad
can be used to recall a specific memory channel between
000 - 049, 100 - 149, 200 - 249, etc. up to 949.
Alternatively the UP/DOWN keys may be used to
sequence through MEMORY CHANNELS WHICH
CONTAIN DATA ONLY, the [DIAL] may also be rotated with
the same effect.
When [SCAN] is pressed a second time, the receiver
returns to MANUAL mode and the memory data is
transferred to VFO where it may be monitored or used as
the starting point to tune from. To return to MANUAL mode
without transferring the memory contents press [MANU]
instead.
When [SCAN] is pressed a second time and held for more
than 1.5 seconds, the receiver enters scan mode and
starts looking for active frequencies in the currently
selected memory banks.Alternatively the [UP] or [DOWN]
keys may be pressed and held for more than I.5 seconds
at this point initiate the scan process.
If an active channel is located, the scan process will wait
until the channel clears before continuing. You may force
the scan process to continue or reverse in direction by
using the UP/DOWN keys or [DIAL].
The sequence [2ndF] [BANK] (in other words the selection
of BANK) has three different effects depending on the
operational mode of the receiver at the time the sequence
is keyed.
Manual Mode
If the sequence [2ndF] [BANK] is keyed in manual mode,
the legend “BANK” is displayed on the top left corner of
the LCD with a bank number. The bank number represents
the current MEMORY BANK where you want data to be
stored during memory write, the receiver automatically
increments to the first available empty location in the bank
selected. Use the UP/DOWN key or [DIAL] to select the
memory bank starting point for memory write, to accept
the selection press [ENT]. This sequence is not essential
as the bank may always be specified during memory write,
however this facility may increase the speed of data entry
at critical times when there are plenty of interesting
activities to save in the memory bank.
Search mode
If the sequence [2ndF] [BANK] is keyed in search mode,
the legend “BANK” is displayed on LCD with a bank
number. The upper and lower limits of search pair are
displayed with the legends “HI” and “Lo”. Use the
UP/DOWN key or [DIAL] to select the desired program
search bank, pressing [ENT] or [CLR] will have the
receiver to search the selected program search bank.
Scan mode
If the sequence [2ndF] [BANK] is keyed in scan mode, the
legends “BANK’ and “CH” are displayed in the left corner
of the LCD. The receiver will pause on the currently
displayed channel for about 30 seconds before resuming
the scan process. The UP/D0WN key, [ENT] key or [DIAL]
may be used to force the scan process to resume. The
sequence [2ndF] [SCAN] with the [SCAN] key held for
more than 1.5 seconds, causes the B110RB to enter the
scan bank link menu regardless of whether the receiver is
in SEARCH, SCAN or MANUAL operational mode.
[MANU] - manual mode
Pressing the [MANU] key places the receiver into a known
operational condition ready for data entry. The display
legend “MANUAL” appears towards the top right of the
LCD. If you are ever unsure what operation mode you are
in, press the [MANU] key. They key sequence [2ndF]
[MANU] place B110RB into HYPER SEARCH mode.
[UP] /MHz /SER - key
This is used to enter decimal point during frequency input
through the numeric keypad. [UP] key may be used to
force the receiver to reverse the direction of search or
scan. The key will also act as an upward tuning control.
The key is also used to select menu options on LCD
whenever it is appropriate.
The key sequence [2ndF] [UP] places the receiver in ready
status to clone data to another B110RB.
