● International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
Operational Instructions and Training Guidelines
● To ensure optimal performance and compliance with the occupational/controlled environment
RF energy exposure limits in the above standards and guidelines, users should transmit no
more than 50% of the time and always adhere to the following procedures:
● Gain of antenna must not exceed 3.5dBi for VHF and 5.5dBi for UHF.
● Antenna Installation: Install the mobile antenna at least 100 cm away from your body, in
accordance with the requirements of the antenna manufacturer/supplier.

Signaling Introduction
The radio supports the following signaling. You can ask your dealer to make appropriate settings on your
radio. For detailed information, please contact your dealer.
HDC1200
The HDC1200 signaling is compatible with the MDC1200 signaling, and realizes functions such as PTT
ID (Encoding & Decoding), Emergency (Encoding & Decoding) and Selective Call (Encoding &
Decoding).
Encoding:
1.
Hold down the PTT key during normal voice communication to send PTT ID.
2.
Go to the menu “Contact List” and select a required contact. Then hold down the PTT key to send a
selective call (Private Call/Group Call/All Call).
For encoding, the radio will provide the following indications:
„
PTT ID/Selective Call: Your dealer can program whether the radio sounds side tone during encoding
or sounds beeps after encoding.
„
Selective Call: During encoding, the LED glows red, and the LCD displays the appropriate call icon
(Private Call:
; Group Call:
; All Call:
).After encoding, the LED glows
orange.
Decoding:
For decoding, the radio provides the following indications:
„
PTT ID: After decoding, the LCD displays the icon
and ID or alias of the transmitting party.
„
Selective Call: After decoding, the radio provides the following indications:
Alert:
The radio will sound default alert.
LED:
The LED glows green.
LCD:
If your dealer enables the feature “Display Decode ID”, the radio will display the
appropriate call icon (Private Call:
; Group Call:

) and
alias of the transmitting party (ID of the transmitting party will be displayed if it is not in
the contact list). If your dealer does not enable the feature “Display Decode ID”, the
radio will display the appropriate call icon only.
