The Waterbug operating instructions show that the unit can be turned on or off with the thumb switch, modes are changed by toggling the switch, and water contact activates the strobe function when armed. Keep the battery-door O-ring clean and free of debris to maintain watertight integrity.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eRelated ACR Firefly PRO references include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3971.3\u003c\/strong\u003e — Firefly PRO Waterbug, carded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3971.4\u003c\/strong\u003e — Firefly PRO Waterbug, bulk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3970.3\u003c\/strong\u003e — Firefly PRO SOLAS, carded, manual activation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3970.4\u003c\/strong\u003e — Firefly PRO SOLAS, bulk, manual activation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe main reason to choose \u003cstrong\u003e3971.3\u003c\/strong\u003e is the automatic water activation.
