When using the FNB-64 Ni-Cd Battery Pack
To install the battery, hold the transceiver with your hand,
so your palm is over the speaker and your thumb is on
the top of the Belt Clip. Insert the battery pack into the
battery compartment on the back of the radio while tilt-
ing the Belt Clip outward, then close the Battery Pack
Latch until it locks in place with a "click."
To remove the battery, turn the radio off and remove any protective cases. Open the Battery Pack Latch on
the bottom of the radio, then slide the battery downward and out from the radio while tilting the Belt Clip
upward slightly.
Battery Charging
Install the FNB-64 Ni-Cd battery pack onto the transceiver. Ensure that the transceiver is switched off.
Plug the NC-76 into the AC line outlet.
Insert the transceiver into the NC-76; the antenna jack should be at the left side when viewing the charger
from the front.
If the transceiver is inserted into the NC-76 correctly, the RED indicator will glow. A fully-discharged pack
will be charged completely in 15 hours.
When using the optional FBA-25 Battery Case
The FBA-25 Battery Case allows operation of the VX-246 using six "AA" size Alkaline batteries. When install-
ing batteries, inset the (–) end first, then press in the (+) end so the battery snaps into place. Always replace all
six batteries at the same time.
To install the Battery Case into the transceiver, follow the same procedure as used for the Ni-Cd Battery Pack,
described previously.
Note: The FBA-25 must not be used with rechargeable cells of any kind.

IGNALING UMBER
Switch on the transceiver by rotating the VOL control clockwise out of the click-stop. For now, adjust the VOL
control to about mid-position (12-o'clock); later you can adjust the level to suit the operating environment.
Rotate the CH knob to select a channel for operation.
To transmit, press the PTT (Push-To-Talk) button. Hold the radio 3 ~ 5 cm from your mouth, and speak in a
normal voice into the microphone.
Note: While you are transmitting, the LED indicator will glow red continuously. Do not transmit on a BUSY
channel (where the LED indicator is blinking green); wait until the channel is clear (no blinking green LED).
To receive weak stations better, disable the squelch momentarily by pressing and holding in the MONI
button on the side of the radio for one second. With the squelch disabled, the LED indicator will blink green
and channel noise and weak stations will be heard. To quiet the radio again, press and hold in the MONI
button for one second.
When your communication session is finished, switch off the radio by rotating the VOL control to the fully
counter-clockwise position (into the click-stop).
Note: The VX-246 can be programmed for DTMF Paging operation (this requires the optional FVP-25 Encryp-
tion/DTMF Pager Unit), and also for CTCSS and DCS operation. Each of these modes provides different
levels of selective calling. Refer to the "Changing the Channel Data" section for details.
DTMF Pager ON/OFF (requires optional FVP-25 Encryption/DTMF Pager Unit)
DTMF Pager operation allows paging and selective calling, using a user-programmed DTMF tone sequence. When
your radio is paged by a station bearing a tone sequence which matches yours, your radio's squelch will open.
To enable or disable the DTMF Pager, press and hold in the [ A ] key for two seconds;
When you hear a "low tone" beep followed by a "high tone" beep, the DTMF Pager is now activated.
When you hear a "high tone" beep followed by a "low tone" beep, the DTMF Pager is now disabled.
CTCSS/DCS Bell Operation
When this feature is activated, the Bell will ring when a station calls you whose transceiver is sending a
CTCSS tone or DCS code which matches that set into your Decoder.
To enable or disable the CTCSS/DCS Bell Operation, press and hold in the [ B ] key for two seconds;
When you hear a"low tone" beep followed by a "high tone" beep, CTCSS/DCS Bell Operation is now
activated.
When you hear a "high tone" beep followed by a "low tone" beep, CTCSS/DCS Bell Operation is now
disabled.
Voice Encryption (requires optional FVP-25 Encryption/DTMF Pager Unit)
When the optional FVP-25 is installed, the VX-246 can be operated using voice encryption for privacy during
communications.
To enable/disable the voice encryption feature, press and hold in the [ C ] key for two seconds;
When you hear a "low tone" beep followed by a "high tone" beep, voice encryption is now activated.
When you hear a "high tone" beep followed by a "low tone" beep, voice encryption is now disabled.
Keypad Locking
The VX-246's keypad may be locked out to prevent accidental changing of its settings.
To lock out the keypad, press and hold in the [ D ] key for two seconds;
When you hear a "low tone" beep followed by a "high tone" beep, the keypad is now locked out.
When you hear a "high tone" beep followed by a "low tone" beep, the keypad locking is now canceled.
How to activate the Programming mode.
1. Turn the radio off by rotating the VOL control fully counterclockwise (into the click-stop).
2. Press and hold in the [ A ] key; while holding it in, turn the radio on.
3. Press the key the function of which you wish to change, then program the new setting according to the
procedures described below.
4. When re-programming is finished, turn the radio off by rotating the VOL control fully counter-clockwise (into
the click-stop).
DTMF Paging
Programming Your ID Code
Your radio's ID code is the three-digit code which your radio will send out when paging another radio.
1. Activate the Programming mode.
2. Press the [ A ] key.
3. If you wish to enable the Auto-Respond Paging feature, press the [ ] key. If you wish to disable the Auto-
Respond Paging feature, press the [ # ] key.
4. Enter the three digit code that you want to use for your radio's ID from the keypad.
Programming DTMF Paging Code
The "DTMF Paging Code" is the three-digit code of the station you wish to page, which your radio will send out
during Pager operation. Ten different Paging Codes may be stored into Paging Memory registers, allowing you
to page ten different stations (or groups of stations).
1. Activate the Programming mode.
2. Press the [ A ] key, then enter the DTMF Paging Code memory number ("0" ~ "9") to be programmed from
the keypad.
3. Enter the three digit code Paging Code from the keypad.
Operating Channel
You may change the operating frequency (from among the eight available channel frequencies) of the channel
selected by the CH knob. This function may be useful if you wish to change the order in which the frequencies
are selected by the CH knob.
1. Activate the Programming mode.
2. Rotate the CH knob to select the channel on which you wish change the operating frequency.
3. Press the [ B ] key, then enter the frequency number from the keypad.
CTCSS Operation
"CTCSS" is a selective calling system which uses a continuous, very-low-frequency tone that is filtered out so
as not to be heard. If many stations are using the same channel frequency, CTCSS will keep your radio's
receiver squelched until a CTCSS tone is received matching the CTCSS tone you have selected for your
33 210.7 Hz
radio. If CTCSS is turned off, any signal received can open your radio's squelch.
34 218.1 Hz
1. Activate the Programming mode.
35 225.7 Hz
2. Rotate the CH knob to select a channel on which you wish change the CTCSS configuration.
36 233.6 Hz
3. Press the [ C ] key, then enter the two-digit CTCSS Tone number from the keypad.
37 241.8 Hz
38 250.3 Hz DCS and ARTS* Operation
00 CTCSS
"DCS" is similar in use to CTCSS, except DCS uses digital codes for more reliable operation. "ARTS" is a
Off
transponder feature, available when DCS is engaged, which will alert two ARTS-equipped radios when an "Out
of Range" condition exists. The stations can then move to a better location to re-establish communications.
1. Activate the Programming mode.
2. Rotate the CH knob to select a channel on which you wish change the DCS configuration.
3. Press the [ D ] key.
4. If you wish to enable ARTS operation, press the [ ] key. If you wish to disable ARTS operation (DCS
operation only), press the [ # ] key.
5. Enter the three-digit DCS signaling number from the keypad.
This procedure initializes the transceiver into its factory-default configuration (the settings installed before you
used if for the first time). In the event of erratic behavior, resetting the microprocessor may clear up any corrupt
Off
date, often restoring normal operation. However, any customized settings will have to be re-programmed.
1. Turn the transceiver off.
2. Press and hold in the [ A ] and [ D ] keys while turning the transceiver on.
3. Press the MONI button to initialize the transceiver.
