Detailed Information

The SL1600 is a digital two way radio from Motorola. A compact radio, the SL1600 is built to IP54 standards meaning not only does it have an ingress protection against dust, but can also withstand splashes of water. Military Standard (MIL-STD-810 C/D/E/F/G) means that the device is rugged and reliable, being able to withstand tougher conditions in the workplace.

With a 99 channel capacity, the SL1600 can operate on both UHF and VHF frequencies. An active view display is present on the front of the device, also having a programmable button to allow the users to customise an option for this radio. VOX Voice Activation capabilities allow for the SL1600 to be used hands free, ideal for working situations where you may need to make contact but don’t have your hands free.

Coming with a 2300mAh Li-Ion battery, the SL1600 has the capability to last up to 14 hours of digital use. With Micro USB Connectivity, this allows for efficient charging and easy programming of the radio.

Features Explained

Lone Worker Feature

Lone Worker is a feature found on many two way radios where it's able to send a pre-determined signal, for example a distress call or alarm, to other radios in range, Lone Worker requires some type of interaction from the radio user after a period of radio inactivity. An example of this is the radio can be set to require the radio operator to interact with his or her radio once every 30 minutes. If they fail to do so, their radio will start making an audible sound. If there is still no interaction with his or her radio within 1 further minute, a alarm will sound to other team members to tell them a team member is not responding to Lone Worker. The supervisor can then dispatch another team member to the non-reponsive team member's last known location to offer assistance.

 Lone Worker is built-in to the Motorola SL1600.

Digital Basic Privacy

Basic Privacy uses a fixed "key" which is set when the radio is programmed, of which there are 255 possible "keys". Whilst this level of privacy is technically basic encryption, it's nevertheless relatively insecure. Comparable to analogue 'inversion' scrambling, it will prevent the 'casual' listener from hearing anything, but does not guarantee against eavesdropping.

 Basic Digital Privacy is built-in to the Motorola SL1600.

Channel Scanning

Channel scanning enables the user to monitor a number of channels and respond when a transmission comes through. The scan feature can usually be programmed to include or exclude channels from the scan. Scanning fewer channels makes the scan faster.

A common example is when there is a private channel and community channel programmed. This is usually the case for a shop which is a member of the local business crime reduction (or shop-watch / pub-watch) scheme. The radio would "scan", or alternate between, both channels. Normally, they might only use channel 1 for their own private use within the organisation. But when a transmission (or call) comes through on the local business crime reduction (or shop-watch) scheme channel becomes active. Then within a few seconds the radio would revert back to it's original channel 1.

Digital hybrid radios can usually scan either or both digital and analogue channels simultaneously. This allows for an extremely flexible scan facility where the user can monitor many channels across both analogue and digital modes.

 Channel Scanning is built-in to the Motorola SL1600.

Voice Activation (VOX)

Voice activation, commonly refered to as VOX, allows the user to initiate the radio to transmit, simply by using their voice. Some radios only allow VOX capability via an external audio accessory such as an earpiece or headset which is VOX-enabled or has a VOX button.

Activating Voice Activation or VOX

There are two possible ways of enabling voice activation (VOX). The first is that we can program a VOX-enable / VOX disable button on the radio. The other option is that we supply an audio accessory, an earpiece or headset, that has a VOX button. Contact us for more information about this.

Programming May Be Required

There may be programming required to activate VOX on your radio. In any event, please talk to our knowledgeable staff and we will be able to offer advice on VOX activation.

 Voice Activation (VOX) is built-in to the Motorola SL1600, but a VOX-enabled audio accessory, such as an earpiece or headset, may be required.
