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

the country of purchase. 

It is important to connect the mains supply in accordance with the information given. 

SEE BELOW. Ensure that the rear panel mains voltage statement indicates that your equipment is 
suitable for your mains supply voltage and that the mains supply fuse is correctly rated. The fuse as 
supplied is correct for the voltage setting. 

WARNING:

This apparatus is intended for use when powered by the HY02-B power supply unit.  

Other usage will invalidate any approval given to this apparatus if, as a result, it ceases to comply with 
the edition of BS6301 to which it was approved. 
 

WARNING:

The equipment B.T. plug 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 B.T. plug should be disconnected from the telecommunications network 

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 ‘NTTP’ and ‘Handset’ must not be connected directly or 

indirectly to the unbarriered ports, ‘Line Input’, ‘Line Output’, or ‘Remotes’. 

This equipment conforms to the safety regulations specified by use of the CE 

Mark. 

Voltage Setting Checks 

 
The rear panel of the equipment carries the Serial Number of the machine. The 

operating voltage of the 

HY02 Digital

 is selectable by a switch on the power inlet port. Ensure that the 

machine operating voltage is correct for your mains power supply. The safety specification of your 

HY02 Digital

 complies with local requirements and must be earthed through the mains connector. The
