INTRODUCTION

The Ericsson GE MTL-SX radio is a high-quality mi- croprocessor-controlled synthesized portable FM radio. All transmitter and receiver functions are controlled by the mi- croprocessor-based circuitry.

The MTL-SX radio’s sturdy die-cast aluminum case has rotary volume and channel controls on its top panel and three

(3)recessed push-buttons which provide scan control on its front panel. A indicator light on the front panel lights when the radio is transmitting and flashes when and the radio is scanning. A recessed emergency button is located on the top of the radio. All personality features are programmable with the PC programming software.

FEATURES

∙16-Channel Capability - The preprogrammed channels are selected with the top mounted rotary Control Knob.

∙Scan Capability With User Selectable Scan List - Using two (2) of the buttons on the front panel, the operator can add and delete any the programmed channels to the scan list. Priority-one and priority- two scan channels can also be selected. A thrid button on this panel is used to toggle scan operation on and off.

∙Volume Control Knob - This rotatable control provides quick and easy adjustments to the volume level. Minimum volume levels can be programmed into the unit to prevent missed calls due to a low volume setting.

∙Monitor Button - This side-mounted button is used to disabled squelch and if programmed for the se- lected channel, it is used to toggle CG and/or T99 operation on and off.

∙Emergency Channel Feature - An emergency channel can be programmed into the radio for GE- STAR emergency signalling. GE-STAR emergency signalling is activated by the recessed Emegency Button on the top panel of the radio. GE-STAR can also be activated by a lanyard connected to the UDC (Universal Device Connector).

∙GE-STAR Compatibility - The radio can be pro- grammed to transmit GE-STAR ID at PTT key, at PTT unkey, or both. 16,384 individual ID codes are available.

∙Programmable Multi-Tone Channel Guard (CTCSS) - Channel Guard tone frequencies within the range of 67 Hz to 210.7 Hz, including all of the

standard EIA frequencies, can be programmed for encoded/decoded operation.

∙Programmable Multi-Code Digital Channel Guard - Similar capability as with tone Channel Guard is provided.

∙Two-Tone Sequential (T99) Decode - Selective calling decode is enabled or disabled on each indi- vidual channel.

∙Channel Busy Lockout - Personality information includes transmit disable capability on a channel where carrier activity is present. This feature is selectable on a per channel basis.

∙Programmable Carrier Control Timer - A pro- grammable transmit timer will automatically dis- able the transmitter and provide an alerting tone after time-out. This feature prevents radio damage and unnecessary channel traffic in the event of a "stuck" mic. The CCT is reset on every PTT.

∙Programmable Transmit Power Level - Transmit- ter power level is PC programmable into the radio (high or low) on a per channel basis.

∙Squelch Tail Elimination - Squelch and audio cir- cuits are designed so that annoying squelch pops which may occur at the end of received messages are minimized. This feature is compatible with ex- isting STE systems.

∙Alert Tones - Alert tones prompt the operator of various radio conditions such as channel access, CCT time-out or a low battery.

∙Programmable Through The Universal Device Connector (UDC) - The entire operation of the radio can be field customized by programming the unit using an IBM PC or compatible computer. The programmed personality is stored in non-volatile memory within the radio.

∙Simple Remote Control Capability - External ac- cessories can be connected to the UDC such as a headset, a speaker-mic or a lanyard. Connection of the speaker-mic allows the operator to remotely control PTT operation and audio level of the exter- nal speaker. An antenna jack is located on the UDC for the connection of a remote mounted antenna such as when the radio is used in a vehicular charger or repeater.

∙Meets MIL-810C and D Specifications - The sturdy die-cast aluminum case is designed to seal out moisture, blowing rain and other harsh envi- romental factors.

∙Battery Packs - Several different battery pack sizes and capacities are available. Intrinsically safe bat- tery packs are available for use in hazardous envi- ronments.
