Hi Nathan,
Thank you for your comment. I have raised a case for you in order to document your query
00450361
In regards to your post we are unable to replace lost remotes as this is not covered under warranty, the reason the projectors are designed without an on/off switch is to prevent theft. I appreciate the atmosphere is busy and it is not always possible to keep track of the remotes.
Your can speak to a re-seller who may be able to offer you a deal on a bundle of spare remotes, to find a re-seller please go to www.prometheanworld.com and click how to buy.
If you would prefer to contact us directly, please go to www.prometheankb.com >area e.g. Projectors, Software > Contact Us. Please include the above reference number in the Existing Case Reference Number field.
Many thanks,
Craig
