Using Multiple Expansion Panels (KP-12 Only)
When using multiple expansion panels, some MOD numbers may have to be reassigned so that each group of 4 keys has its
own unique MOD number. Table X shows the correspondence between MOD numbers, key numbers, and setup pages.
Example 1, connecting one EKP-20 along with a KP-12. Use the default MOD numbers as shown in Table 4 on page 40.
Next, assign setup pages. See “Top Level Menu, Page (1-4)” on page 22.. You should assign one setup page as MAIN. This
page will correspond to the keys on the KP-12. Assign a second setup page as “EXP1”. This page will correspond to the first
16 keys on the EKP-20. Assign a third setup page as “EXP2”. The first 4 keys on this setup page will correspond to the
remaining 4 keys on the EKP-20. The remaining 12 keys on the setup page are not used. If you want to connect LCPs, you can
use one LCP-12 and one LCP-20 without changing the ROMs.
Example 2, connecting two EKP-20 Expansion Panels along with a KP-12. From Table 4 on page 40 you can see that the
EKP-20 has default MOD numbers 5 through 9. One of the EKPs must therefore be reprogrammed to use MOD 10 through
14. Also, assign one setup page a “Main”. (To assign setup pages, See “Top Level Menu, Page (1-4)” on page 22..) This page
will correspond to the keys on the KP-12. Assign a second setup page as “EXP1”. This page will correspond to the first 16
keys on the first EKP-20. Assign a third setup page “EXP2”. The first 4 keys on this setup page will correspond to the first 12
keys on the second EKP-20. The remaining 12 keys on this setup page will correspond to the first 12 keys on the second EKP-
20 Assign the last setup page as “EXP3”. The first 8 keys on this page will correspond to the remaining 8 keys on the second
EKP-20. The remaining 8 keys on the setup page are not used. If you want to connect to LCPs, you can use one LCP-12 for the
KP-12 and one LCP-20 for the first EKO-20 without changing the ROMs. You will have to change the ROM in the second
LCP-20, however, to match the MOD number for the second EKP-20.
Menus, SERVICE, MUTE LVL
The front panel speaker is muted by 12dB whenever a talk key is activated. This is done to prevent possible feedback between
the microphone and speaker. Headphones are muted 6dB, also to prevent possible feedback, especially with open-air sty head-
phones. The muting levels for speaker and headphones are independently adjustable as follows:
