Before transmitting
There are many radio stations operating in proximity to the frequency ranges
this product covers. Be careful not to cause interference when transmitting
around such radio stations.
■ Covering ranges
You may expect a range of up to 2 km at high-power when located on a flat,
noise-free place like on a beach. However, it may vary drastically depending
on how to wear and carry the radios,surrounding locations/conditions and static
noise levels (below or near power transmission lines), etc. In urban areas with
many buildings or inside a building, such covering range will become drastically
short even to several tens of meters.
■ About enclosure protection
This transceiver is NOT water and dust protected of any degrees. Avoid
contacts with water and dust, and if wet or dirty, immediately wipe them with a
clean dry cloth. Please also note that the body is small and thin; DO NOT carry
it in your pants pocket to avoid cracking.
■ Lightning
Any person is not safe outdoor during thunderstorm and lightning. This condition
is getting worse if somebody keeps a handheld radio; chances of being hit by
lightning are doubled since lightning may hit a radio antenna as well. At this time,
there is no handheld radio having any kind of protection against lightning current
(which is higher than10 kA.). Note also that no car provides adequate protection
of its passengers or drivers against lightning as well. Therefore, Alinco will not
take responsibility for any danger associated with using its handheld radios
outdoor or inside the car during lightning.

4. CTCSS/DCS
CTCSS and DCS are used to filter receiving audio, and sometimes effective to
eliminate receiving noise. Their functions are practically the same, just different
technology is used. All users in the same group should set the same CTCSS or
DCS code to the units. After setting, only the matching code signal is heard. This
is not a voice scrambling, but just to reduce chances hearing unwanted signals.
Note:
・If there may be a signal that is different from your CTCSS/DCS code on your
channel, even you don't hear it because of CTCSS/DCS function, you can't
transmit. A warning beep sounds in this condition when you press .
Observe the radio icon to see if it shows receiving, or press key to
temporary release the CTCSS/DCS to hear the actual audio. Press key
again to go back to the CTCSS/DCS operation.
・There may be a delay and you miss hearing a word at the beginning of
transmission when CTCSS/DCS is used. To avoid this, press , wait
just an instant then start speaking.
・Press key and press triangle keys to select CodE menu.
・Press key again, CTCSS and flashing 2 digit code appears on the display.
・Press triangle keys to select desired CTCSS (50 codes) or DCS (105 codes)
codes.
・Press or leave it for 10 seconds to set, or press key to return to the
menu. When set, The CTCSS/DCS code remains displayed as shown.
