Safety Information

Safety of Mains Operated Equipment

This equipment has been designed to meet the safety regulations currently advised

in the country of purchase and it conforms to the safety regulations specied by

use of the CE Mark.

Warning : There are no user serviceable parts inside the equipment. If you should ever

need to look inside the unit, always disconnect the mains supply before removing the

equipment covers.

Warning: The HY-03 line socket should only be connected with apparatus

complying with BS6301, and the connection to the network must not be hard wired

Interconnection directly or indirectly with equipment ports marked in accordance with

BS6301 to unmarked ports may produce hazardous conditions on the network and

advice should be obtained from a competent engineer before such a connection is made.

Warning: This apparatus must be earthed by means of the earth connector on the rear

panel, and the connection to the telecommunications network should be removed

before disconnecting the earth. Disconnection of this earth connection may render the

equipment unsafe, with a consequential possible electrical shock hazard from exposed

metallic parts.

Warning: The barriered ports ‘LINE’ and ‘HANDSET’ must not be connected directly or

indirectly to the un-barriered ports, ‘MIC/LINE INPUT’, ‘OUTPUT’ or ‘REMOTES’.

Voltage Setting Checks

The mains input voltage selector switch on the rear panel of the equipment sets the

operating voltage of the HY-03 to be either 115V or 230V. Ensure that the machine

operating voltage is correct for your mains power supply. The safety specication of your

HY-03 complies with local requirements and must be earthed through the mains connector.

Fuse Rating

The HY-03 is supplied with a single fuse in the live conducting path of the mains power

input. For reasons of safety it is important that the correct rating and type of fuse is

used. Incorrectly rated fuses could present a possible re hazard, under equipment fault

conditions. The fuse ratings for the HY-03 are:

115V operation: 200mA 5 x 20mm SB

230V operation: 100mA 5 x 20mm SB

The active fuse is tted on the outside rear panel of the unit. If you change the voltage of

the HY-03, make sure to change the fuse also.
