HeyPhone
Cave Rescue
Communication
System
In 2001, 50 HeyPhone sets were issued to the UK's cave rescue groups.
| January 2007: The HeyPhone documentation on this site derives, for the most part, from material produced during the period 2002-2004. Although still largely correct, documentation may go out-of-date with respect to corrections, obsolete components, updated techniques and peripheral apparatus. Occasionally, updates to this web site may be produced but, as time goes on, this will become less likely. To find out the current status of the project you should subscribe to the HeyPhone discussion forum where you can share your requests and experiences with the wider caving community (assuming, of course, that it reads the forum). |
