The Sanyo CMP-351E was a phone manufactured in Japan and designed for use on the E-TACS analogue network in the UK.
It featured a "high performance helical aerial" and had what Sanyo called "battery saver circuitry" that delivered up to eight hours of standby time or 60 minutes of talk time.
At 260 grams and 215 cubic centimetres, it was described as "slim and lightweight".
The phone could store up to 99 numbers in its phone directory and up to eight "last number redial" records.
