The KH-500 radio contains three (3) buttons on the front panel. The KH-600 contains three (3) buttons along with a twelve (12) button DTMF pad on the front panel. The scan function allows monitoring of any or all channels. Any channel may be scanned with or without a priority level. One channel can be programmed for Priority 1 (P1) and another for Priority 2 (P2), with any or all remaining channels programmed as non-priority channels (S). There is also an Emergency GE-STAR mode transmission capability. A LCD display provides status display of the radio functions along with the display of the selected channel number. 7 The Universal Device Connector (UDC), located on the side of the radio, provides connections for external audio accessories. This connector also allows the radio system personnel to connect programming equipment and program the per-channel and overall radio features. Consult the radio dealer to determine the programmed features of your radio. Features that are programmable on a per-channel basis include: • Receive Frequency • Transmit Frequency • Channel Busy Lock-Out • Optional Squelch Tail Elimination (STE) for Analog Channel Guard • Channel Guard Encode/Decode (Analog or Digital) • Type 99 Tone Decode • CG/DCG Decode Tones/ Codewords • CG/DCG Encode Tones/ Codewords • Automatic Number Identification (ANI) • RF Power (High or Low) 8 • Microprocessor Oscillator Shift in Receive mode • Microprocessor Oscillator Shift in Transmit mode • Channel Spacing (12.5 kHz or 25/30 kHz) • Telephone Interconnect DTMF Keypad enable (KH-600 only) Features that are programmable on an overall radio basis include: • Display Backlighting • Alert Tones • Emergency GE-STAR (with or without Home Channel) • Three (3) DTMF Auto-Dial Telephone Numbers (KH-600 only) • Carrier Control Timer (CCT) • Hi/Low RF Power Button Enable/Disable • Scan Options • CG Auto/Manual Reset • A.N.I.

April1, 1999 Federal Communications Commissions Authorization & Evaluation Division 7435 Oakland Mills Road Columbia, Maryland 21046 Attention: Equipment Authorization Branch Subject:: Type Acceptance FCC ID: AXATR-382-A2 Members of the Commission, Ericsson Inc. request the Type acceptance of the AXATR-382-A2 mobile radio. The AXATR-382-A2 is a conventional mobile radio that operates in the 403-512 MHz band at a power range from 1 to 4 Watts with a Frequency Stability of +/- 2.5 ppm. The AXATR-382-A2 operates in both narrow and wide band modes and comes in three splits (403.0 - 440.0 MHz), (440.0 - 470.0 MHz), (470.0 - 512.0 MHz) the middle split was tested and is representative of the other two splits. This radio exist in a DTMF and scan version. All test have performed in part 2 and part 90 pursuant to the Type Approval requirements.
