OTHER FEATURES

MIL-STD 810 C/D/E The TK-481 meet or exceed tough U.S. Department of Defense environmental standards in addition to Kenwood's own technical and industrial standards.

DIE-CAST CHASSIS The monocoque aluminum die-cast chassis-heat sink borrows a principal from aircraft construction for rigid strength.  Surrounding this and forming an integral part of the chassis, is the super-tough polycarbonate case to provide years of durability.

WEATHER-SEALED UNIVERSAL CONNECTOR The universal accessory connector and battery contacts use spring action gold-alloy elements for excellent contact, conductivity and anti-corrosive properties.  The universal connector is designed to mate with Kenwood audio accessories such as the KMC-25 and still maintain the MIL-STD 810 C, D & E.

WEATHER-RESISTANT Elements like the polyvinyl keypad membrane and speaker cone prevent moisture penetration for confident wet weather use.

HIGH OUTPUT AUDIO The TK-481 has  an extra large 1.58 inch speaker element and half waft of audio power that provides robust clarity in noisy crowds and industrial environments.

EXTRA-LONG BATTERY LIFE The KNB-1 6A 1100 mAh and KNB-1 7A 1500 mAh batteries deliver better than 8 and 1 0 hours life respectively on a single charge (5-5-90 duty).

WORLD CLASS PERFORMANCE Take a look inside and compare!  You'll see a culmination of over 50 years of world class design experience that gives the TK-481's their excellent receiver and transmitter characteristics making them equally at home in urban or rural environments.  The high stability oscillators, efficient MOS-FET power modules and advanced filtering are only part of what gives the TK-481 both the protection and power to become the key complement to any well designed radio system.

DOT MATRIX LCD DISPLAY The 12 character LCD employs simple easy-to-read alphanumerics and icons for operational and status indications.

TEN CHARACTER ALPHANUMERIC A full 10 character alphanumeric represents each talk group, division, department or site name.

LIGHT CONTROL manual and auto-shutoff control of the key back-lighting and LCD lamp facilities safe nighttime operation without excessive battery drain.

HOME SYSTEM/GROUP At the press of a key, the radio unit is instantly reset to a primary trunk site (or channel) and talk group without having to switch system and group controls.  This functions is extremely useful in multiple system/group programmed radios (fixed revert).

MULTIPLE SCANNING FUNCTIONS System scan and group scan permit monitoring multiple systems and talk groups for calls.  Priority scanning is available within pro-grammed conventional systems.  Scan lists can be altered with the Add/Delete features.

KEY LOCK Prevents missed calls due to accidental system/group setting changes.

MIL-SPEC SPEAKER MIC WITH UNIQUE CONTROLS When a KMC-25 MIL-SPEC speaker microphone option is attached it forms an integral part of the radio and meets all the same MIL-STD 810 C, D & E specifications as the radio.  A screw mount connector provides a secure electrical and mechanical binding and weather-resistant seals, O-rings and bushings keep out moisture, dirt and grime.  The KMC-25 has two unique top keys that can be programmed for repetitive user functions such as home select, monitor or high/low power.  The recessed orange key is ideally positioned as an auxiliary emergency ANI key since calling in for assistance and emergency are usually related actions.

CELLPHONE DIALING FEATURES DTMF keypad models include dialing features for telephone and/or PBX access such as 32 memory auto-dialer with alpha-tags, store and send, last number re-dial, and more.

PC PROGRAMMING AND TUNING Radio parameter programming and tuning can be accomplished via the universal accessory connector from a PC-compatible computer without ever having to open the radio saving both time and expense (KPG-35D software and KPG-36 cable options required).

SELECTIVE CALLING A built-in feature, DTMF decode allows a supervisor or dispatcher to selectively "page" individuals and groups via numeric codes (millions of codes possible).  Even TK-481 keypad models can perform this for portable-to-portable selective paging. This feature is economical to implement in any radio system.

OVER-THE-AIR DISABLE Another part of the DTMF decode feature is the disable function whereby individual units can have their transmitter or both transmitter and receiver disabled by sending it a pre-programmed disable code.  This provides a simple method for rendering lost or stolen portables useless.  The unit can be re-activated the same way.

CUSTOM KEYS The TK-481 portable offer a choice of twenty-seven programmable feature settings that can be assigned to any one of seven keys allowing the radio to be customized for either simple or elaborate user needs.

HIGH CAPACITY DESIGN The 32 system and flexible group capacity accommodates multiple-site and talk-group organization for any type private system or commercial network.

FLASH ROM ADVANTAGE Planning for the future of system architectural changes and custom needs, the Kenwood TK-481 portable has main and reserve Flash ROM memory caches to accommodate Kenwood enhanced protocols for networked systems and advanced feature sets.

ENCRYPTION CONTROL Add secure voice communications for law enforcement or private security.  An internal port permits addition of optional modules to provide voice scrambling from low level inversion to high level encryption types.  The radio's pro-gramming provides both automatic and manual control for clear and coded modes.

DIGITAL ANI AND EMERGENCY CONTROL Unit ID and emergency ANI for computer-aided dispatch operations can be added with optional modules.  The recessed orange key is specifically designed for emergency ANI triggering.

RADIO PASSWORD Preventing unauthorized use of lost or stolen portables, this feature requires a four digit access code to be entered every time the radio is powered up (DTMF keypad models only).

ANTI-PIRACY CODED RADIO LOCK PROTECTION Prevents portable cloning and extraction of the radios program information without the proper technician entered six digit password.  This data transfer password is a system managers first line of defense against piracy and enhancing system security.

EMBEDDED MESSAGE Deep inside the radios Flash ROM memory, an electronic message can be stored containing owner identification, property I.D. numbers, user and department names, service records, etc.  A radio can be electronically identified even if external labels, markings or factory serial numbers have been removed.
