I saw this recently on a voltage detector.
Problem:
The word “repress” in this imperative is incorrect.
Explanation:
The verb “repress” — spelled R-E-P-R-E-S-S — means to keep under control.
The verb “re-press” — spelled R-E-HYPHEN-P-R-E-S-S — means to press again.
The imperative sentence that appeared on the label of the hand-held device for detecting voltage was directing the reader to press the trigger again after releasing the trigger.
This tells us that the solution should contain a hyphen in the second verb and optionally the pronoun “it” as the object of the second verb.
Solution:
“Release trigger and re-press [it] while touching object.”
