Eartec Co UPMX4GS1
UltraPAK™ Remote Beltpack with Max4G Headset & Battery


Eartec's UPMX4GS1 consists of a one UltraPAK unit matched with one Max4G Single Headset and a Lithium battery. It's an add-on set made to work seamlessly with Eartec's HUB & UltraPAK sets (both sold separately), enabling the addition of another person to an existing intercom system.

YLP1000 UltraPAK Beltpack
The smallest full-duplex transceiver on the market today, weighing in at only 2.5 oz., the UltraPAK is an ergonomic beltpack radio that is designed to be easily integrated into Eartec's UltraLITE full-duplex wireless intercom series. This compact digital transceiver is specifically engineered for those users that need hands-free voice communication using a lightweight headset accessory. It includes a volume control adjustment and a mic mute button with LED indicator that illuminates when gain is set to standby. The included field-replaceable Lithium battery (see below) charges externally and powers the UltraPAK for up to 7 hours in full-duplex mode.

Max4G Headset
A tremendous accessory to your wireless intercom, the Max4G Headset is a single ear configuration (double-ear configuration sold separately). It's a midweight headset that provides a fully-adjustable headband with deluxe foam padding for a firm and comfortable fit. It's boom arm can be rotated 270°, and when set in the UP position, engages the Automute Boom Technology for convenient, automatic mic muting.

Field-Replaceable Lithium Battery
Each UltraPAK beltpack comes supplied with a rechargeable Lithum battery which is installed in a special beltpack compartment. These batteries are lightweight and only about the size of a matchbook. They charge up in about 3 hours and operate the headset for about 6-7 hours. And since they're removable and externally chargeable, they can be swapped out in seconds.

UltraLITE™ HUB Systems
Eartec UltraLITE HUB wireless systems are a professional full-duplex intercom for people that need to communicate and work with their hands at the same time. UltraLITE, The HUB, and  UltarPAK utilize Digital Enhanced Cordless Technology (DECT) to provide professional, simultaneous wireless speaking communication within a ¼-mile range.
