Antenna Basics
Your Mobile Radio Kit does not include an Antenna. It is VERY Important to NOT transmit without a antenna or
dummy load attached to the mobile radio. Doing so, will cause harm to the internal components of your radio.
You will want to choose a suitable antenna for the bands you plan on transmitting and receiving on.
If you plan on transmitting on 145MHz you will want to ensure you have picked an antenna that states it is
capable of working with 145MHz. If an antenna is not properly tuned for the frequency you transmit on –it can
cause damage with the reflected power going back into the radio.
Pick an antenna with SWR of less than 1.5:1 to safely transmit.
Grounding Plane
Antennas require an appropriate grounding plane to properly work.
Magnetically Mounted Antennas
These antennas must be grounded to a metal surface, such as a vehicle body. Magnetic base antennas do not
properly operate unless they are fully magnetically grounded first.
NMO or PL-259 Base Antennas
These antennas will normally require a base or mobile hardware kit. These kits are grounded either through:
drill or clamp inserts on vehicles, magnetically mounted, or available as stationary base hardware kits. Some
antennas may include a base station grounding plane kit.

10 | GETTING STARTED
R Visually Inspect Coax/Connectors for any Slits or Damage –moisture should not be allowed to penetrate
fittings or your coax.
R To maximize the life of your radio, it is important to understand antenna basics before transmitting on
your radio, transmitting without an antenna, or with high SWR (Standing Wave Ration) –can void war-
ranty support.
R An Active SWR Meter is a great tool to have when selecting an antenna for your needs. You can monitor
and confirm that your SWR is within safe levels when setting up your radio for the first time (periodically
checking SWR and your antenna set-up is advised).
Antenna Requirements
Antenna SWR Rating : 1.5:1 or less (on the radio frequencies in use.)
Antenna Impedance : 50 ohm (use 50 ohm rated coax and coax connectors).
Antenna Grounding : Ensure the antenna is mounted with a groundingplane.

Pound # Key (Keypad Lock)
To enable or disable the keypad lock, press and
hold the [#/LOCK] key for about two seconds.
A quick toggle of the # will alternate power levels
from High power to Low power.
The keypad lock will lock both the main radio but-
tons itself and also the handheld keypad.
The PTT/MONI and Power Buttons will not be
locked when enabled.
Star ✱Key
A short momentary press of the key enables the
reverse function (reverses the TX/RX settings ac-
cording to Offset settings).
When listening to broadcast FM a momentary
press will start the scanning. Scanning in broad-
cast FM will stop as soon as an active station is
found.
To enable scanning, press and hold the [✱/SCAN]
key for about two seconds.
Turning the unit ON
To turn the unit on, simply push and hold the vol-
ume knob until it turns on. If your radio powers
on correctly there should be an audible tone after
about one second and the display will show a
message or flash the LCD depending on settings.
Turning the unit OFF
To turn the unit off, simply push and hold the vol-
ume knob until it turns off. The unit is now off.
Adjusting the volume
Toturn up the volume, turn the volume knob clock-
wise.
To turn the volume down, turn the volume/power
knob counter-clock-wise.
R By using the monitor function (MONI button),
you can more easily adjust your volume by
adjusting it to the un-squelched static.
BASIC SHORTCUTS AND USE

R Just because you can program in a channel
does not mean you're automatically autho-
rized to use that frequency.
R Transmitting on frequencies you're not au-
thorized to operate on is illegal, and in most
jurisdictions a serious offence. If you get
caught transmitting without a license you can
and will get fined, and in worst case sent to
jail.
R However, it is legal in most jurisdictions to
listen. Contact your local regulatory body for
further information on what laws, rules and
regulations apply to your area.
Making a call
Press and hold the PTT button on the side of the
handheld mic to transmit. While transmitting,
speak approximately 3-5cm (1-2 inches) from the
microphone. When you release the PTT your
transceiver will go back to its receive mode.
Channel selection
There are two modes of operation: Frequency
(VFO) mode, and Channel or Memory (MR) mode.
For everyday use, Channel (MR) mode is going
to be a whole lot more practical than Frequency
(VFO) mode. However, Frequency (VFO) mode is
very handy for experimentation out in the field.
Frequency (VFO) mode is also used for program-
ming channels into memory. For details on how to
program your transceiver see Chapter 4, Program-
ming.
Ultimately which mode you end up using will de-
pend entirely on your use case.
D Frequency (VFO) mode
In Frequency (VFO) mode you can navigate
up and down the band by using the [UPY] and
Each press (or rotation click) will increment or dec-
rement your frequency according to the frequency
step you've set your transceiver to (Menu Item 1:
Step).
You can also input frequencies directly on your
numeric keypad with kilohertz accuracy. Howev-
er, the radio will floor to the nearest frequency that
corresponds to your frequency step, in other
words, when you input frequencies with greater
than 1kHz resolution (such as 145.6875 MHz in
the example below), always round your input up.
[DOWNZ] keys (or rotating the selector knob).
12 | BASIC SHORTCUTS AND USE

BASICSHORTCUTSANDUSE| 13
D Channel (MR) mode
The use of Channel (MR) mode is dependent on
actually having programmed in some channels to
use. Tofind out more on how to program channels
see Chapter Programming.
Once you have channels programmed and ready,
you can use the [UPY] and [DOWNZ] keys to
navigate between channels (or Rotate the Selec-
tor Knob).
!If you have channels programmed with Transmit
power set to Low, you can use the key to momen-
tarily switch over to high power if you're having
trouble getting through.
Monitor Both VFO & MR Modes
You can toggle from VFO and MR (Memory Re-
call) mode by either pressing the [V/M] button on
the front of your radio, or you can toggle modes
from the Handheld Mic by a long press of the
[MENU] button.
The VFO/MR mode will only toggle on the current
selected A/B/C/D line –while the other channel
lines will remain on channel or memory mode as
they were selected.
This allows you to monitor channel and fre-
quency mode simultaneously.
