A system for performing telemetry of multi-channel biological signals obtained from electrodes attached to a subject, is provided with a transmitter and a receiver. In the transmitter, a converter converts the multi-channel biological signals to digital data, and a storage stores the digital data. In the transmitter, a first transceiver is operable to transmit a prescribed amount of the digital data stored in the storage, and a battery is operable to supply a battery voltage to the first transceiver. In the transmitter, a switch places the battery in either a first state where the battery voltage is supplied to the first transceiver or a second state where the battery voltage is not supplied to the first transceiver, so that the first transceiver intermittently transmits the digital data. In the receiver, a second transceiver is operable to receive the digital data transmitted from the first transceiver. The received digital data is to be reproduced multi-channel biological signals at an output device.
