On the front, the FK201 has 4 toggle switches controlling various functions useful to data input and which seem to be typical of these types of keyboards. These switches appear to have the following functions on the FK201:

:* 自動 デュープ/スキップ - オン or オフ (Automatic Dup/Skip - On or Off)
:* 自動 レコード前進 - オン or オフ (Automatic Record Advance - On or Off)
:* プログラム　数字シフト - 全文字 or 数 字 (Program Numbers Shift - All Characters or Numbers)
:* カタカナ　シフト - オン or オフ (Katakana Shift - On or Off)

[[Topre_switches#Switch_Variations|Topre 'Hi-Pro' switches]] are used for all keys except the bottom row, which use standard Topre switches. This is common practice for all of Topre's Hi-pro switch boards, it seems. On the back, there are two height-adjustable feet and a volume dial which presumably controls the internal speaker. Inside the board there are three PCBs.

===Variants===
The FK201 was made available in 2 layouts, '029' (FK201-JS) and '[[JIS]]' (FK201-JK). The manual mentions the 029 keyboard being used for punch cards, which makes sense as the secondary functions on the keys appear to be very similar to those found on the [[IBM]] 029 Key Punch system<ref name="datum_2"/>. The JIS model appears more suited for general data entry purposes.
