    Your ‘Contact’ form doesn’t work for sending emails. I want to know if the 302R works with 9 or 7.2v rechargeable batteries. Thanks

      The contact form is being looked into, since it works for many people but not some. I think it has something to do with the Captcha code timing out if it takes more than a minute or two to fill out the comment field and submit. You can always email us at sales@erostek.com also.

      The ET302R and ET232 can use rechargeable 9-volt batteries, but for best results, we recommend alkaline batteries for these units. Never attach a 9-volt battery eliminator (aka “adapter”) in place of the battery in any case. The 302R (remote) unit operates on batteries only. No adapters can be used in place of this, and a bright yellow warning label is also there to remind you under the battery cover. I hope this helps!
