The encoder is now setup for proximity encoding only. If you are using a computer 
based system, you should select proximity only for your card technology. 
Encoding Keys 
Refer to your system user manual for detailed instructions on encoding, as this 
manual only deals with the actual presenting of the key to the encoder. 
Magnetic Stripe Encoding (HT22iP only, HT Proximity Only) 
When prompted for magnetic stripe encoding, insert the keycard into the slot of the 
encoder, then remove the keycard. If an error occurs, the encoder will beep and 
display the error message. If the encoding is valid, no error beep is given and the 
card is ready for use. 
Proximity Encoding 
When prompted for proximity encoding, present the proximity card or token to the 
Prox Logo on the encoder. When the encoder is ready to encode a proximity key, it 
will begin to beep. Present the card at the logo point shown below. The encoder will 
emit a louder beep when the encoding has been completed.
