AM / FM RADIO TRANSMITTER KEYFOBS • • • • • • • • • Highly Secure Protocol 1 – 3 Switch Options Led Indication Of Transmission Directly Compatible With Keeloq Decoder Power Saving Auto Shut Off Feature Automatically Transmits Battery Low Condition. User Customisable Housing Board Level Programming Of Id Range: ⇒ AM-315MHz upto 50m ⇒ AM-433MHz upto 100m ⇒ FM-433MHz upto 150m • EMC & FCC Compliant DESCRIPTION The RF Solutions KEELOQ range of miniature pocket Keyfob encoders are available as Radio of Infra Red transmitters. When paired with one of the KEELOQ Rx decoder boards, a complete remote control system may be achieved, with comprehensive interfacing capabilities. This may also be high security “code hopping” The keyfobs are housed in a tough ABS enclosure and supplied with Battery ready to operate. An membrane overlay sticker is used to indicate the switch positions which may be customised to incorporate a specific logo or mark.

Operation of the Tx encoder buttons will cause either a momentary or a latching action at the Rx decoder, depending on the configuration of the Rx decoder. Battery Supply The keyfob is supplied with a standard cigarette lighter 12V battery type GP23A or equivalent. Low Battery When the unit measures a low battery voltage level, the data transmitted includes a ‘Low battery’ status flag to the receiver decoder. DS110-5 Sept ‘06 ©2006 Reg. No. 227 4001, ENGLAND Page 2 AM / FM RADIO TRANSMITTER KEYFOBS Auto Shutoff Feature After ~26seconds of continuous transmission the Keyfobs are programmed shut down. This is to prevent the battery being drained through accidental operation (i.e. if it is in the users pocket!). This feature can be removed by re-flash programming of the unit. License Exemption The transmitter encoders use EMC compliant radio transmitter modules and complies with ETSI330-220 and ETSI300-683. USA : This device complies with part15 of the FCC rules. Operation is subject to the following two conditions: 1. The device may not cause harmful interference, and 2. This device must accept any interference received including interference that may cause undesired operation.
