Hi Bob,
The colour and fascia concept is fine-looking and acceptable but Rounded triangle or square button naturally user friendly looking while other shape look harsher and unfriendly. Also, you will notice on today modern gadgets and application icons, they were all rounded square.
Our suggestion, to let them do as our request and then compare it, maybe we can see the difference then we can decide.
1. Just try then to make it rounded rectangle , the LED and words are inside the rounded rectangle so it will not make confusion. Arrangement of LED will be discussed later.
2. Are the printer and screen are defined by other suppliers? If so, those right angle are match with rounded square button.
3. Yes, we agree that button should be arranged properly. Rounded square button will do also the operation if proper distance allowance for the fire fighter user with protected glove.
4. May be we keep this as it is.
5. Zone LED display make it rounded rectangle and the rest it okay.
