F5 function key is not working in SAP ITS screens

Hi experts,

We are using SAP ITS RF and wavelink browser on intermec CK3x devices. We are having an issue with F5 function key. When F5 is hit, the screen just refreshes and it does not do the intended action. It looks like the key code "F5" is not being recognized by ITS template.

In the ITS template, we have maintained the following meta tag for "F5".

<META HTTP-Equiv="OnKeydispatch0x74" content="Javascript:setFKey('5');">

The keyboard test gives the following key codes for "F5".

F5 = 3F00 under the keyboard test

F5 = 0074 under the windows keyboard test

Am I missing something.?

Thanks in advance.
