A2 / B2 / C2 / E2 (Standard) Control Head:

• Some A2, B2, C2 or E2 heads may have buttons installed in the plugged spots, depending on what the individual radio code plug allows.

A4 / B4 / C4 / E4 (Rotary) Control Head:

A5 / B5 / C5 / E5 (Standard or Enhanced) Control Head:

A7 / B7 / C7 / E7 (Standard or Enhanced) Control Head:

	Small Keys - A4 - A5 - A7
	A4 Rotary Control Knob

• The full size keys are also used on the A9, B9, C9 and E9 control heads.
• The rocker keys are also used on the A9, B9, C9 and E9 control heads with the newer plastic fronts.
• Only the conventional model numbers are shown in the above table to save space. The trunking models shown above each control head face drawing also apply.
• Keep in mind that the code plug determines which control head type the radio can use. For example, even if you were to replace the blank hole plugs in a B2 control head with keys, the radio's B2 code plug would still not let you use them. The same thing holds true if you put a control head with A7 front plastic on a radio with an A5 code plug.
• Some B2/C2/E2/A5/B5/C5/E5/A7/B7/C7/E7control heads have DIM and HOME printed on the front plastic (as shown in the above examples) and some control heads do not. There are keys with DIM and HOME printed directly on the key for the control heads without the printed labels. There is a blank key for the control heads with the printed labels.
• The A4/B4/C4/E4 control heads have unique DIM and HOME keys.
• Standard, Rotary and Enhanced are the RSS settings for each type of control head. The Rotary is always an A4, B4, C4 or E4. The radio's code plug determines the control head type for Standard or Enhanced (A5/B5/C5/E5/A7/B7/C7/E7). I do not know for sure, but I do not think there are any Enhanced B2, C2 or E2 control heads (the radio's code plug would determine this).
• The keys and knobs above with labels are dedicated to those functions and can not be changed in the RSS.
