The Display

CAG Btech V2 Radio Usage/GMRS Page 3of 6
Battery Level Indicator
When the battery level indicator reads the battery is depleted. At this point the radio will start beeping
periodically as well as flash the backlight of the display and when voice prompts are enabled, a "Low Voltage"
announcement will be heard, indicating that you need to change your battery or put your radio in the charger.
To get an Accurate Voltage reading you Press and Hold the button (for about 2 seconds), the display will show
the current voltage level of the battery.
Status LED
The status LED has a very simple and traditional design. When you receive a signal, it turns green, when you
transmit it turns red, and it's off in standby.
Side Key 1 [F]
Press [F] momentarily to start the broadcast FM receiver. Another momentary press turns the broadcast FM
receiver off. If a signal is received on the active frequency or channel while you are listening to the broadcast
FM, the receiver will open squelch to that frequency (as if scanning) and remain there until the signal goes
away; it will then switch back to broadcast FM.
Side Key 2 [M]
Press [M] momentarily to turn on the LED flashlight. Another momentary press will flash the LED. Another
momentary press turns the flashlight off.
Dual Push-To-Talk
The GMRS-V2 includes a Dual PTT Key/ Rocker Switch. You can communicate with other parties effortlessly by
pressing the PTT rocker key upwards to transmit on Channel A (the upper display), or by pressing the PTT rocker
key downwards to transmit on Channel B (the lower display).
Power And Volume
Before we turn the power on, make sure you have attached the battery and antenna.
Turning the unit on
To turn the unit on, simply rotate the volume/power knob clockwise until you hear a "click". If your radio
powers on correctly there should be an audible double beep after about one second and the display will
show a message or flash the LCD depending on settings for about one second (see “38 PONMSG - Power on
Message” in Appendix B, Menu definitions). Then it will display a frequency or channel. If the Voice
prompt is enabled, the voice will announce "frequency mode" or "channel mode".
Making A Call
Press and hold the PTT button on the side of the radio body to transmit (upwards for CHANNEL A; downwards
for CHANNEL B). While transmitting, speak approximately 3-5cm (1 to 2 inches) from the microphone. When
you release the PTT, your transceiver will go back to receive mode.
Channel Selection
There are two modes of operation: Frequency Scan Only (VFO) mode, and Channel / Memory (MR) mode. For
normal use, Channel (MR) mode is going to be a whole lot more practical than Frequency (VFO) mode. (We will
only cover Channel mode in this document.)

Turning the unit off
Turn the volume/power knob counter-clockwise until you hear a "click". The unit is now off.
Adjusting the volume
To turn up the volume, turn the volume/power knob clockwise.
To turn the volume down, turn the volume/power knob counter-clockwise. Be careful not to turn it too far, as
you may inadvertently turn your radio off.
Dual Watch - With Dual Push-to-Talk Enabled (Default)
In certain situations, the ability to monitor two channels at once can be a valuable asset. The
BTECH GMRS-V2 features Dual Watch functionality (single receiver) with the ability to lock the
transmit frequency to one of the two channels it monitors.
The Dual Push-to-Talk Switch is a Rocker Switch with upper and lower buttons.
To Transmit on the Upper Frequency (VFO A) – Press upwards on the Dual PTT Button
To Transmit on the Lower Frequency (VFO B) – Press downwards on the Dual PTT Button
Menu And Function Keys
The MENU key is used to enter the menu and confirm menu options.
The UP-ARROW and DOWN-ARROW keys are used to navigate through the menu as well as select channels and
step up or down in channels.
The EXIT key also switches between A (upper) and B (lower) displays. The frequency or channel on the selected
display becomes the active listening and transmit frequency or channel. There will be an arrow next to either
the frequency, name, or channel number to show which band is active When listening to broadcast FM, the
EXIT key switches between 65-75 MHz and 76-108 MHz bands. The EXIT key is used to exit menus and cancel
menu options. For a more in-depth explanation on how to use the menu see your manual.

Some Basic Radio Procedures (paraphrased from the AGRC documents).
Every user must use their designated FCC Call Sign at intervals prescribed by the FCC. For GMRS
licensees, that is at the end of any conversation and every 15 minutes during longer conversations.
Use of the full call sign at the beginning of a conversation is not necessary since that is not an FCC
requirement. HOWEVER, we do require that stations identify at the beginning of the conversation with
their suffix (the numerical part of their FCC call sign) and if no contact, then sign off with their full call
sign. How that works is something like this example:
“714 this is 903” (In this case, I am calling fictional user WQIV714.) If there is no answer I might
repeat it a couple times: “714 this is 903. Are you there, Bill?” If no answer, then I would sign off
saying: “No Contact WQRV903 clear”, or “Negative contact WQRV903 clear and monitoring.” Or, just
“Nothing heard WQRV903 clear.” This lets everyone on the air know who I am and that I am done
trying to reach “Bill”. The channel is now open for use by others. Each user has their own variation on
this protocol, but everyone should use this protocol or an equivalent of it especially when using
repeaters.
Family members may use unit numbers or tactical IDs (like “base”, “mobile 1”, “mobile 2”, etc) when
calling other units under the same license. However, at a minimum of every 15 minutes and at the end
of the conversation, all units in a conversation MUST identify with their full FCC call sign and unit
number. If a family member is communicating with a station not on the same license, then all parties
must also use their full call sign and unit number, if any.
If you transmit for a brief period of time, for testing, to check if you can hit or “kerchunk” a repeater, or
for any other reason, you are always required to identify with your full call sign. This is a courtesy to
others and a requirement of FCC regulations.
