Motorola APCOR

The Motorola APCOR could transmit voice and EKG simultaneously and was battery operated.

There were three or more versions of the Motorola APCOR, the first was similar to the Biophone, the second was significantly smaller and was white.

Additionally many units were optionally equipped with a keypad on the right side of the carry handle.

This was used to send DTMF tones to the repeater to turn it on and change channels[citation needed].

The Motorola APCOR was discontinued in the 1980s and was soon phased out in favor of cellular phones that could transmit EKG and voice.
